Ok let me explain what happens if you play Giannis 1-1
Boston is a slow pace, low scoring team. In the play offs against good defenses like Indiana and Bucks they average 104 points and give up only 85 possessions to the opponent. So you need to generate 105 points out of those 85 possessions to beat them.
Giannis currently averages 17 FGs. He only takes 17 because he passes a lot, but if he sees only one guy guarding him he will attack way more. I'd say at least 25 times, minus a couple of charges and turnovers, lets say 21 FGs. And there will be no BS three pointers when you guard him 1-1, these will all be drives to the rim where he averages 57%. If you add his usual free throws that's 35 points for Giannis, but that's based on his average minutes of 32 per game. If he plays 39 minutes like he did last game in Boston everything goes up proportionately, and then you're looking at 42 points from him only.
That leaves 64 field goals for the rest of the team, and we know 40% of them will be threes. If you add their usual free throws, it means they need to be collectively kept at 37% from the field for the Bucks to score under 104 points and lose the game.
And best of luck with that, even Sterling Brown shoots 41%.
Khris/Bledsoe/Lopez/Connaughton/Hill are all around 50% since the play offs started, only Mirotic is 43% because he had those crappy games coming back from injury. You try to keep ALL of them to 37% and inevitably at least one of them will get hot and torch you. Like I said, good luck with that
