The end result of this spring's practice sessions is that the Frogs do not have a clear-cut backup QB, and the competition for the #2 job between sophomore Matt Brown and redshirt freshman Trevone Boykin will continue this fall. It is highly likely, even, that we'll see both receive playing time in relief of Pachall.
There are a few ways you can look at this. If you're the pessimistic, "sky is falling" type of fan that most TCU supporters seem to be, this could be taken as a sign that the Frogs are in serious trouble if Pachall goes down because no one has impressed the coaches enough to claim the backup role. Then again, it may be that both have been good enough that the coaching staff cannot yet come to a consensus about which one would be better if thrust into action.
Still a third option is that the coaches know who their #2 guy is for 2012, but are reluctant to slap the "heir apparent" tag on someone right now in an attempt to keep all of the young QBs hungry and determined to become the starter when Pachall eventually departs the program.
