The thing is though, many of the guys we call "diamonds in the rough" aren't projects, they're studs from small schools who were mostly undiscovered. Jonthan Banks, 2 star, pick 6'd Tebow twice in one game as a true freshman. Nickoe Whitley, low 3 star, was an instant beast after redshirting. Gabe Jackson, low 3 star who was an early OL contributor. Dillon Day, 2 star, early OL contributor. Benardrick McKinney, 2 star, instant beast after redshirting. The list goes on. None of these guys were two or three year projects; they were all ready to play immediately or after a redshirt year, which in many cases was due to good depth. Our recruiting rankings aren't relatively low just because we take chances on a ton of project guys, but also because Mullen and co. are very good at identifying obscure, low-rated players who would be 4 or 5 stars if they played at a bigger or more visible high school.
Also, you have to consider the effect heavy in-state recruiting has on our ratings. Many of these guys are just as good athletically as guys from states with excellent high school football programs like Texas, Georgia, Florida, and even Alabama, but are rated lower because they aren't as polished at their positions, when all it takes in many cases is a redshirt year to get them up to speed. A 4-star redshirt freshman from Texas who sits because of depth and a 3-star from Mississippi who sits because he isn't quite ready can easily end up being the same contribution-wise by the time they both step on the field.
