I think there are two separate answers because there are really two different questions:

Who should it be? Spud, He adds a great dimension to the offense. He seems even better than Dantrelle Savage. He made some phenomenal plays against Texas to keep us in the game, and his huge break against Mizzou helped to catapult us onto the national stage.

Who would it be? Dez, because of his flashy plays as a kick returner, which should be unrelated to becoming an all American receiver, score him huge points and give him a larger spotlight. He is extremely talented but his route running skills still need some work before he gets to that level, but I will savor every moment until he does. He is one of the most exciting receivers to watch because of his jump ball skills.

Here's an interesting question:

Zac Robinson does not have the strongest arm on the team. He is most definitely the best quarterback. So, why not put Brandon Weeden in for the last play of the game against Texas? Texas knows that you are just going to chunk it deep. Why not put the quarterback in that can throw it 60 yards?

About the O-line I definitely agree. O-lines and D-lines are probably the most overlooked parts of teams. It all begins with them. The spread offense is much easier to handle with a good D-line, but on the other side any running back could average 4 yards a carry behind a great line.

I see your point about Robinson being a leader, but I don't think chemistry comes into play here. This was a situation where the quarterback does nothing more than throw it towards the endzone(not that it's easy just that it doesn't involved reading routes or coverages really) and pray that one of his receivers comes down with it. If Robinson were inside the 40 I don't think it is even a question. With him in closer range you definitely give it to Robinson, but this play is almost entirely about arm strength and somewhat about accuracy with the deep ball. Robinson just doesn't have the arm strength to make that play at the end of the game. This isn't an insult. He just doesn't. Brandon Weeden does. Other than maybe offensive line play, how does leadership and chemistry come into play here? Are the receivers going to having a shorter vertical leap? Are they going to not run as fast? Weeden doesn't have to hit them in stride, so routes or comfort with knowing your receiver's speed doesn't come into play. I understand that chemistry has everything to do with timing and confidence that your quarterback can put the ball between defenders in traffic, but this isn't that type of play. So, why not for one play just for arm strength put Weeden in?
