I believe myself to have fairly balanced view of Graves and the FO -- I know/beleive that he has taken the fall for many historical decisions that werent necessarily his--
that being said, that fact that the team's draft evaluation missed so badly on a day one pick is a mistake that will be placed squarely at his feet. Yes, I would rather them "fess up" and get the error behind them instead of keeping a worthless player on the roster simply to make it less embarrassing, but it doesnt fix the bigger mistake.
Picking up Moses might be a great move -- however, it has a high degree of luckiness with it rather than design. Its like having 19 in blackjack and hitting. Drawing a 2 doesnt make hitting the right move.
