Because he is 20 months removed from being basically unrecruited by every power 4/5 team in the country. He sits out a year, then is one of 2 running backs, a team with a running QB, on the FCS national championship team. They played in 16 games and while his 244 carries and 1181 yards looks impressive, it is literally 15 carries for 73 yards per game and 4.8 ypc. Emmitt Johnson in the last 3 games of the regular season and the bowl game rushed for 314 yards on 59 carries 5.3 ypc. In the last 4 games, the FCS playoffs, Brown had 55 carries for 216 yards, 3.93 ypc and 1 TD.
I don't necessarily have anything against this player, I just don't believe he is the difference between 7-6 and 9-4. I definitely do not believe he is worth getting into a bidding war. And if he wasn't a local kid, no one on the forum would be concerned at all about this guy. Everyone on here, myself included, complains about not winning games yet when it comes down to picking up a transfer player or a HS recruit, it appears it is more important to overpay for a local player than to go all in on a national recruit.
