Immensely physically talented, but streaky and his head had gone in Detroit. Hit niggling little injuries and a collapse in form as Det were about to hand him the keys to the franchise, thus stepping back from their intention to shop Howard, which seeemed to mess with his head.
More capable of getting an impossible shutout than many starters, but has fundamental technical issues that reappear, and goes through periods of massively positionally over-committing.
Had his RFA salary been more reasonable the wings probably would have tried to convince him to stay, but at $4m+ his play wasn't worth it
