uhhh. If he doesn't use his redshirt during the year he has to sit out, he only has 1 year of eligibility left. A transfer year has to burn eligibility, either through redshirt or a year of eligible. If he transferred now and did not take a redshirt during that year, he would only have 1 year left to play (RS year you don't play) so he wouldn't take a carry until 2013 and then have to enter the 2013 draft. If he takes the redshirt during his transfer year, he has 2 years to play, 2013 and 2014.
I thought he was born in 91-92 like all the other 2009 guys, he is older and was born in 1990. You are still wrong about how the redshirt and transfer works though. He would only be 24 when drafted (birthday, sept 20 1990, draft would be april 2015, 24 years and 8 months)
A solid back is going to get around 25 carries per game.
