I'm a little late to the game here, but Mitch Mustain, former Arkansas quarterback is said to have some interest, or rather, Tech is said to have some interest in Mustain.
I'm going to go out on a limb here, but I don't think there's any way that Mustain comes to Lubbock. He would love the number of times that Tech throws the ball, but he would have to sit out a year (his sophomore year) and would have one year to play, behind Harrell and before Potts. This is the same kid who's dad complained that the Arkansas offense wasn't utilizing his son's talents. If it's me, I let this one go.
Personally, I'll take my chances with the crew that we have. There's certainly an understanding amongst the quarterbacks that we have here that if you're patient then you'll play, at least for one year. I don't know that Mustain will have the same attitude.
