I've been alluding to how great and underrated Zo is but I haven't made a full post on it yet. It's pretty odd that looking around you can find write ups either here or from blogs about other players. There's nothing on Zo. I mean articles from professionals from back in the day exist but for some reason I can't find any breakdowns on Zo which is a shame because his impact was tremendous and at his peak he was on the same level as young Duncan, arguably better than Malone who barely won MVP over him, and was comparable to Shaq at the time (who played no defense).
Offensively Zo had a basic post game, and a pretty reliable jumper out to 15 feet (it was shaky outside of that). That's basically all (of course he had the signature Georgetown running hook like Ewing did but it was meh). Most of his points were gained due to his immense physical advantages. His turnaround was money because of the speed of his spin, he got deep position easily with his strength and finished strong, and his faceup drives worked because he had a jumper you had to play while having one of the best first steps for any C ever (Dwight comes to mind as faster). Zo also wanted it, and he played like it. Got him to the line often and got him a decent amount of putbacks. He was undersized but I think that played to his advantage more especially in the post Shaq era. He was in a league environment where teams kept a big plodder on the floor or on the roster and when matched up with one he was unstoppable. He didn't even need his jumper against some of the bigger guys in league history.
His handles weren't great, he wasn't a great mover laterally, he didn't have spin moves or a strong drop step, but he still managed to be a 19-23 ppg scorer on between +5-7 rTS% each of the first 8 years of his career and a 20 ppg on 55 TS% guy in the playoffs.
He didn't pass well at all but Miami in both 98 and 99 had a +2.5ish offense. They had a +2.4 offense in 98 against NY and a +0.9 in 99 against them (that's slight underrated because NY's defense came alive in the playoffs). All in all Zo wasn't great but he was definitely a good enough first option to give you a top 10 offense that would hold in the playoffs against some tough ass squads in tough ass series (arguably the toughest series' ever) if he was the centerpiece with a very good PG and decent third scorer (Tim and Mash).
Overall he averaged 20.1/11.0/1.6 with 3.9 bpg on +5.3 rTS% with a 107 ORTG in the regular season and 21.6/8.2/0.8 with 2.8 blocks and 1.6 steals per game on 57.1 TS% (+8.3 rTS%) with a 106 ORTG (+8 rORTG).
Defensively he's on the shortlist of the GOATs. He was DPOY back to back in 99 and 2000 and watching him it's obvious why. He was someone that chased shots but didn't seem to foul because his jump speed was so fast. Next to Bill Russell he's the most effective shot blocker ever. One thing I always noticed watching Zo is he kept the ball inbounds. If his back was to the basket he went straight up and only flicked his wrist. If he was behind the play he pinned it on the backboard. Either way he always found a way to keep it in play and I'm taking him as the best rim protector ever next to Deke. In this clip you can see exactly how fast he gets off the floor and how effortless it is for him.
His only weakness was his lack of height. Unlike Ben Wallace who seemed to be able to overcome his height issues Zo was not a great man defender at all. Usually this isn't an issue but Zo played at the same time as numbers 4, 9, 18, and 23 on this list. The 4 guys with the highest single season PPG totals for any true C outside of Wilt and Kareem. In these clips you can see how Shaq dominates him at both player's arguable peaks.
Hakeem (who was also undersized - he was listed at 7 feet but is barely taller than Dwight Howard who is 6-9 barefoot and 6-10 in sneakers) is the only one of those centers Zo played well and that's because with his speed and power he was the perfect counter to him. I'd argue no one ever played Hakeem as well as Zo did in the few times I've seen a game featuring the two. Overall he's a 10/10 rim defender, 10/10 help defender, and maybe a 7/10 man defender that still led -4 to -6 defenses at his best.
As far as the season goes it was a lockout but Miami won 33 of the 50 games, going 1-3 without Zo, and lost in a major first round upset to the eventual NBA Finalists while they still had their best player (because Ewing got hurt and they still made the Finals without him). I think that result is why this year is overlooked because Zo played amazing in that series while his team collapsed.
Zo averaged 21.6 ppg on 57.1 TS% like mentioned before but his team? Outside of him they scored 57.4 ppg on 47 TS%. Tim Hardaway went from averaging 17.4 ppg and 7.2 apg on 51.1 TS% with a 13.8 TOV% and 105 ORTG to 9.0 ppg and 6.4 apg on 35.7 TS% with a 22.2 TOV% and 74 ORTG in the series against NY. Without Zo dominating NY sweeps them instead of needing a lucky bounce on an H20 floater to win.
As far as his impact goes I'm not going to dig for the raw +/- numbers (screw NBA.com for ever taking them down) but Zo led the league in RAPM and his yearly finishes from 97 to 99 are:
97 - 7 (this is NPI)
98 - 2 (3rd in NPI)
99 - 1 (2nd in NPI)
TL;DR: Impact stats paint him as the impactful player of that 3 year stretch.
Basically we have it all here, just not the reputation, and that's something recent because in 99 he was runner up to MVP and in 2000 he was 3rd in MVP voting to Shaq and KG. The numbers hold up, the playoff performance holds up, the team strength success holds up (not in 99 specifically but form 97-00), the impact holds up. If it wasn't for his game being limited compared to the other star Cs of his time and him losing head to head matchups against all of them constantly (besides Hakeem) he'd be seen as on their level pretty clearly. As it is he's a half step behind them as the next best great true C if you ask me.
EDIT: And I forgot to mention Zo's impact as a leader. I'm not the biggest intangibles guy unless it bleeds on the floor and boy did it when Zo was out there. He's one of the toughest players ever (he would fight you if he needed to as JVG found out in 98), one of the most well respected players ever (so respected people forget what he did to the Raps to get back to Miami and just like him going back to Miami), and one of the players that played hardest in league history. If I made a short list of players with the most contagious energy in the floor Zo would probably be right under Magic, KG, and Westbrook as far as guys worthy of this list go. He always seemed to lead through big plays, big celebrations, and a crowd/team that exploded when he was ready for them to. I think it's a big part of why that Heat team was so successful and of course we all know while Wade was the best player on the 06 Heat and Zo didn't even start he was the soul of the team turning around each game when he hit the floor.
