Go with the youngsters?

What's you guys take on benching players like Donnie Welter and some of our other vets who've underperformed in place of some younger guy? I thought Deculus and Charles looked good, Taylor and Phillips have played well and maybe even handing the keys over to Brennan. I'm not sure if the second half play calling was just O being his normal putrid self or that there's just no confidence in Etling on 3rd and medium to long but if the latter is the case Brannan needs to start. To me Florida was offensively inept and when we face the meat of this schedule I don't have much confidence we can win games. Why not follow the Uga example and take our lumps with our youngsters so that next year we can be competitive? Maybe even upset some of the tougher opponents this year if things click for Brennan. Even if he has a few turnovers his ability to push the ball downfield maybe a productive tradeoff.
