Trust me - Without great coaching, if you never, ever land 4 star or 5 star recruits (yes, we have gotten a few 4 stars over the years), winning more than losing is VERY difficult. The recruiting stars DO mean something, but they are not the end all. Mistakes and errors are made when recruiting star evaluations are determined. IF they were the end all, Bammer would win going away in every game. (FYI - they do in most)
Lastly, a great QB can make a big difference when playing with less talent overall. Brady proves that year in and year out.
