4 years max for Griffin is scary for me. His injury history is not good, and he seems to be aging quickly. I like his game... I just wonder what will be left of him in 3-4 years. I don't want to sign a player for max who plays 50 games a year.
Hayward is entering his prime years, IMO he'll get better. He has no injury history, he's an underrated defender, has great positional size.
If we could get a youngish legit center that requires 20-25 minutes a game, we could let Horford play some minutes at PF, and he could play center when we go small. We'd have an answer when we loose the boards, and are dealing with the huge centers in the league.
i went with Hayward.
