This player moves well on his film. I don't know about the level of competition but it will be interesting to see how he adjusts to GP's defense. He could be someone that gets early playing time if he makes the transition well enough.
Also, obviously, Nebraska fans are a proud bunch so I am not surprised there may be a couple bitter fans out there. Really, they are a good bunch and would like to see them return to the Big12 and get the old rivalries going again. With regard to Frost, I suspect he'll do better in year 2 and it will be even more interesting to see how much he can improve Nebraska in the years thereafter. Good Nebraska football teams are good for college football so I hope things work out for Frost.
