Re: It appears Luke Del Rio is leaving
The only way this makes good sense is if Del Rio was told that he would not play next year, period. And that does make some sense, because if Del Rio did play, he would count against the scholarship limit. If Del Rio didn't play at all next season, he would then become a redshirt sophomore that didn't count at all against the limit. So, it's possible that he was told it was unlikely that he played, or simply that the numbers wouldn't work out.
This is pretty confusing, considering he was third string, and looked like he had a good shot to compete for the starting job. I expected one or two of the QBs lower on the depth chart to transfer, but I've seen it mentioned that one QB lower on the depth chart knows that they had little chance to start at the FBS level, so it's hypothetically possible that the refusal of another QB to transfer forced Del Rio's transfer. He might just have hated the type of offense Kiffin was going to install, though...
What I'm hoping though, is that this was done to pave the way for Coker to come in. Coker wanted assurances he was going to start apparently, and while this isn't quite that, the first and third string QB leaving really gives him a great shot. It goes without saying though, that we have to hope someone else lower on the depth chart steps things up and develops, because depth at the position is important and Coker will be a junior.
