First off, he did tear his achilles, that's not something you can just pretend didn't happen. Second, imo, even without that injury I don't think he's a max player. Of course I could be wrong, but I have a hard time believing a team would have offered him a 4 year/141 Million dollar contract. The best he could do was 1 year 3.5 Million, I know it doesn't matter to you, but if the league viewed him as a top 3 center, surely someone would have offered him a better contract, the fact the best he could do was 1 year/3.5M should tell you all you need to know
