That's not a smart way to look at recruiting, there's a million reasons why some schools offer kids & not others.
You never recruit a kid based on who else is recruiting him. Kareem Hunt went to Toledo & still wound up as one of the best backs in the nation & one of the best in the NFL. Darrell Henderson rushed for 1900yds last year at Memphis, Devin Singletary rushed for over 4200yds in 3 years at FAU... There's great backs all over the country, just because Parrish isn't going to Bama, UGA, Clemson, Oh St or LSU doesn't mean he's not going to be a beast in college.
Pitt has Shady McCoy, James Conner & Dion Lewis in the NFL, it's not like they're some FCS school that never puts players in the league. And in all honesty it doesn't matter what school Parrish is committed to, he's one of if not the most productive backs in Dade, he rushed for over 2,000yds last season & is already about to crack that number again this year or at least get well over 17-1800yds total.
If we're taking 2 backs in this class & RB is a position we need depth in & there's a kid that plays at a school just a few minutes away from your campus it's kind of a no brainer you go after him.
