I'm thinking they couldn't swing a trade to move up for Bowers because a couple teams didn't want to lose out on getting a quarterback. Minnesota and Denver definitely had their minds made up to pick a quarterback. Minnesota even moved up a couple spots to ensure they get one.
Watching an interview with Marshall Faulk he brought up an interesting scenario regarding Aaron Donald. Aaron said something about not wanting to go through another training camp. Faulk questioned whether or not the team secretly told him he could retire, avoid camp and they could have a spot for him if he wanted to rejoin the team at some point.
Its just a thought. But hey, if training camp was the main reason he retired you gotta wonder if he's open to joining them for a run at another ring. Imagine the defense going into the playoffs with Donald, Fiske and Turner in the middle surrounded by Verse and Young.
