Perhaps.
However, in order for the coaching staff to have screwed up, we have to assume that each WR competing for that one spot during TC gave the exact same effort while on the clock, mastered each detail identically, and put in the exact same amount of work study while off the clock. If that wasn't the case, and the evidence we have -while admittedly circumstantial -stongly suggests that it wasn't, then how can cutting Rogers be on the staff? This is a textbook case of a guy not doing enough to make the club if there ever was one.
