It's chicken/egg scenario. GS isn't getting 4 and 5 star kids right now, he has to win first. E.g. develop and coach up 3 starts, start getting 8/9 wins per year, then he can start reeling in the higher rated kids.
His current method of recruiting underrated guys will not work if he aspires to get to the OSU/Bama type level, but he has no choice right now except to do it this way.
Since he's a pedestrian game day coach (great program builder though, with a proven track record of getting guys to the league), he'll have to rely on quality assistants to help him in the day to day operations, while becoming more of a CEO rather than on field coach (which he's clearly starting to do).
Anyone that thinks we're winning anything big with this method (short term or long term) is nuts, none of the big boys does it this way and star rankings are here for a reason. Yes there are exceptions, but look at Bama's roster, it's filled with 4 and 5 star guys.
Ask any coach, x's and o's are nice but you win with the Jimmy's and Joe's
