I said this last year when Nichols Lost the starting job, he aint staying and looks like I was right on, It sucks to lose a guy, but lets all be honest once bradford cemented the job last season and halzle ensured he was the  backup, nichols musta felt a bit wasted at OU he probably wasn't gonna play at least not for a few seasons, he still has a redshirt year left, and with the newest QB recruit for OU looking at least as good as nichols why stay? I wish him the best but I am not surprised

below is the article with the details.
