I'd like to point out that Jonathan Taylor and Montee Ball were both 3 star running backs. A little closer to home, Shonn Greene was also a 3 star. Of these, Jonathan Taylor was the most stupendous miss by the recruiting "experts" exploding to 1977 yards his freshman season.
Also, I'll take this opportunity to point out how dumb it is that Taylor is back this season. He should be a millionaire right now as he easily would have been a first rounder last season. Instead, he decided to 1. shorten his shelf life in the NFL by a year or more, 2. run the risk of injuring himself, and 3. allow scouts to nitpick his game. This all translates to more risk and less money. Dumb.
