One thing I've noticed about Rivals is that they don't seem to measure a player's attitude / aggressiveness on the field. Back in 2004, I remeber watching Ryan Torain from Shawnee Mission NW play on Metro Sports a couple of times during the year. He would run over people and by people as a RB -- he was a big, aggressive runner in HS. However, he was overshadowed on his team by Mike Rivera -- long-haired MLB at the Flaw on the Kaw now. Torain was barely in the Rivals database in '04 and was a 2-star player. I just had a feeling back then that he'd make a good DI RB. Well, after going to Butler CC, he ran for almost 1300 yards / 5.5 YPC for Arizona State as a true junior this year.
Of course, they gave Matt Boss four stars because he ran fast at an OU football camp. But, if you ever saw his HS tape, he was a titty-tapper blocker, and not even a good one at that.
The couple times I saw Mack play this year, he was a very aggressive player with a pretty good motor. He has soft hands and liked to get after it on defense. Bottom line is that I think Rivals is being lazy with this guy just like they were with Ryan Torain a couple years ago. Both players don't have the flashiest of HS stats, but you can tell they have a nose for football if you'd seen them play.
