Your post is a ridiculous regurgitation of context-less stats.
Perine was the leading rusher for UF last year, which leads to his number of attempts and total yardage.
Travis Home was Miami's leading rusher last year, and he had more carries and total yardage than Perine.
Thus, you are trying to UF's leading rusher to Miami's second option. Which is just stupid.
The point is much simpler. Dallas is a RB moving from second-most-used to (possibly) our most-used RB. Attempts and yardage will increase if that happens. It would be one thing to compare Perine to, say, a UM RB who had barely played last year. In that case, you could potentially make the argument that Perine's experience is worth more than a Miami freshman's "potential".
But 5.7 yards per carry and 6.2 yards per carry are both good.
If you are looking at the TOTAL running back situation, though, you have to look beyond an apples-to-oranges comparison of just 2 players.
Look, I happen to think that UM's returning RBs Dallas, Davis, and Lingard are better than UF's returning RBs Perine, Pierce, and Davis. You can try to throw stats out there, but you are also ignoring that there will be a lot more rushes and yardage available for UM because we are replacing Homer, as opposed to UF replacing Scarlett.
