Numerous stats studies been posted on this blog correlating being a college FB starter or an NFL draftee with recruiting evaluation stars.
However, for the Falcons and Pats. These two teams have less 4 and 5 star ranked starters than expected. (compared to percentages from the NFL draft, prior Super Bowls, and Pro Bowl). Edit (originally wrote "more starters were unranked or rated 2 stars (12 total) than 5 stars (three total)")
Julio Jones, Martellus Bennett, and Malcom Brown were the only starters who were rated 5 stars coming out of high school.
Alan Branch from UM was a 3 star. Tom Brady was the only starter who was recruited before the star system was widespread--author retroactively gave him a 4 star.
Edit: title changed from "more 3 stars" to "less 4 & 5 stars"
