No doubt he will have to prove himself. I'd say that though he only attempted 21 passes last year, he did complete 18 of them and looked really good in the time he did have on the field last year. From what I can see, he's vastly improved since his freshman year.
I dont know if 5'10 is generous, but both OU and the A's measure him as 5'10 195. I dont know if they both stand to gain much from embellishing on that but i suppose it doesnt matter in the end. His height isnt gonna be changing so he's stuck with whatever it is. If he can play he can play, his height wont be a huge factor. his frame might be a much bigger factor than his height if it comes down to it. I dont think he'll have to run all that much next year, I bet he wont even have 500 yards rushing. I'd rather let the running backs do much of that, but the threat of Murray running will be huge. Changes how you have to play D to defend that possibility. It'll be fun to see him running against texas, if someone can actually catch him and lay down a hit one of two things happen: he gets up and goes on wiht his day, or he is out of the game and enter Kendall. Either way, win-win for me.
Come on, man. You seem like you follow college football. If you think that Murray is going to run around on college defenses like he did in high school, and especially against a good defense like Texas has, you're being blindly biased.
