He does seem to roll around on the floor looking like someone shot him more than anyone I've seen (then return 2 minutes later). However, there's obviously something really wrong with him now. Seems like it would have been a good idea to let it go an extra week and hope to salvage something from the season. They're not winning much without him at 100%.
They're going to be even worse next year when he's gone. Fran is lucky he got hurt this summer or he probably would be playing overseas now
