I am a transplant from Austin Texas and UT Longhorn football follower since 1994.
I have seen Sam play for four years at the University of Texas and here is what Chris Ballard saw in this kid:
1- I foresee Sam being our 4th down threat. He can run and throw on 4th and goal line option.
2- He is really smart, intuitive and emotionally very strong. As a freshman he brought UTexas back in the 4Qtr in the Rose Bowl, after the starter was injured. Watch the tape on You Tube. When he runs he is under control and like Luck he has a linebacker body.
3- When Chris Ballard says, he has the "it" factor I agree.
I am anxiously waiting to see him play this preseason.
Maybe in the past, but I can tell you a lot of guys made those types of catches last Sat. when I was there and I've seen some other examples from camp on these vids people are posting.
Seems like there have been a ton of underthrown balls though. Some maybe by design, but certainly not all.
