THIS...IS...NOT...TRUE!
I am not sure how many times this has to be said. One player, only one player ahead of Sims was "lost". That's Phillip Sims, (unless you count AJ who Sims backed up). One, the rest, that whole list, including Del Rio, was a bunch of guys that were behind Sims for a reason. They were not all busts, they were not all talentless, but they were behind him. It's not opinion, it's the depth chart...
You seem to be caught up on the idea that Blake at QB wasn't necessarily the first choice, and that's true, the first choice was Phillip Sims at QB. But, he transferred, and Blake impressed, and kept impressing. That doesn't mean anything bad happened, that doesn't mean anything else went wrong. Ely transferred, Del Rio transferred, McLeod transferred... not because they weren't good enough, because Sims apparently was better.
