He put a SF at C, what, combined with Patient tactic, means that he got a lot of FGs, because he had a lot of JS. What is more, your C probably doesn't have a lot of OD, so he couldn't defend Allegri's tries from mid-range. It's also possible that Allegri has some IS, which helped him in close shots. In result, he scored 55% of FG and 56% of 3FG. It was enough to win this game, because the half of all points scored by his team were made by him.
Next time, if you suspect that he'll try to use this trick again, use C with better OD.
