IBL Cos we'd like him to last the whole season and not play in dead rubber or wrapped up games.
Which is completely fair, especially when you see him hobbling around the last twenty minutes of games. But for all of our worrying about him, and his hobbling, he's usually available to start for us. I do think we maybe worry about this stuff a little too much, especially given his track record. I think we have to trust Arteta's judgement with him a little more, after all he will have far more information than we ever will.
And it is true that for all the talk of how he's been relatively quiet this season, his "relatively quiet" is still winning us matches on the regular.
Completely agree that he should be kept away from dead rubber type situations mind.
