Yes, he will.
Imagine Lance bringing up the ball in a playoff game, Pacers are down 1 and Lance starts doing Lance things.
Wether he will do a Milwaukee 4th quarter 1:40 to go thingy or a Raptors 4th quarter 6:24 to go thingy, it's both entertaining
Entertainment fills seats and that is going to save the Pacers franchise until the roster issues will be fixed.
Lance added some fire and toughness to the team, but against the best opponents that isn't going to be enough.
Every improvement is welcome though and he has already made a huge impact, filling in the gap that Bird has created with Turner as starting center. Turner, who isn't ready to contend for at least 2 more years. At least Paul George now has another talented companion, who is ready to contend.
With Lance on the team, the Pacers will make the playoffs, will fight hard to win the series and with all that has happened during the season, Paul George will be a happier person going into the summer than during the season. I can't think of a better way to save this franchise than to make Paul George a happier person.
The beautiful part about the Lance addition is that Lance isn't that great of a player. PG's happiness about Lance isn't going to last.
So next time Paul will feel frustrated about the team (and Lance), it will not be that difficult for Bird to improve the roster again.
PG happy again, extension one step closer again. If Lance were a great player, but the Pacers wouldn't advance because Paul wasn't mentally tough enough (again) to hit his free throws, it would be more difficult to convince Paul George of staying, because it would be much harder to upgrade the roster.
In other words, Lance his flaws will keep Paul George his flaws under the radar and the Pacers can continue to try to upgrade their roster, while they keep the image of PG as Batman alive, knowing he is actually closer to a Robin.
