The Tar Heels have their biggest game of the season coming up next week against the powerhouse that is OU, and the QB battle is still wide open: Coker has the best arm out of three (barely), but is not very mobile. This would eliminate any sort of zone read or scrambling threat from the PB. Watson is a true freshman, and the most raw out of the bunch as far as his arm and mechanics go. He is also the most athletic, and could be a real asset in the run game. Trubisky has been flying under the radar, and he is almost a mesh between Watson and Coker. He is not as fast as Watson, but does have a quick first step. He will also be a lot tougher to bring down, and sports a nice arm. Decisions, decisions.
