My point is is that those star ratings you speak of, with no disrepect to the athletes they pertain to, are just that. Stars. I believe David will be just as athletically competant as those 4 and 5 stars but with two main differences. He will not have an ego which many of them already do, and he will have a complete willingness to learn, a blank slate if you will. Sometimes balnk slates are the easiest people to teach because they don't have bad habits to break. Just my .02 on the star rating.
One other main difference you forgot - most of those 4-5 star players have been playing since pop warner and have competed in various camps and programs that enhanced their ability and improved quality of play. But i agree, if you have an athlete, you can teach them the game - you cannot go the other direction.
Your other points, 100% agree and players like your brother filter through the ranking system every year and then pop up at some small college(not calling NU a small school) and everyone says wow - how did Texas or Florida or USC let him go.....i agree rating system is flawed big time...
And i agree about the blank slate - your perspective on that is right on..... actually you speak in a manner that i think your brother if similar is a much better fit at ISU then Nebraska and not hatin on them. Not sure what Pellini will do over there, they have a lot of quality players, not sure what Callahans problems were but i enjoyed watching Nebraska fans back peddle... I do know that our current coaching staff has taken some decent players especially on our offensive line and molded into a very good unit and it will be even better next year. Given your brothers class, he would have a much better chance of becoming the player you think he will be at a college where he gets to play early - need that trial by fire to establish what kind of player he wants to be....
But, i will leave you with this.... I spoke about your brother's commitment when i saw the article that had him committed to ISU and about him and his physical nature, i thought we had solidified our tackles for the next four years. For your sake and his, i only hope his decision comes full circle and he in fact becomes our bookend tackle to Big Trey.....
