Who's to say he can't be redshirted next year? Then he provides some much-needed maturity and experience for two years AFTER much of the team graduates next year.
Why would you want to? If reports are correct he brings a skillset that we need.
Also, if you redshirt him next year, that means he's 25 before he starts playing his junior season with us. I know we want to be successful long term and everything, but think to age 25/26...i know i wouldn't want to be playing undergrad ball with 18-21 year olds. I would feel old, and I would feel like I would need to move on with life. We don't want that attitude on the team. But since he's 23 now, he's still got a little bit of spunk in his step...
of course this is all speculation, just my own personal opinion. Still, like OUVan said, it sounds like he has a skillset that will be a great asset to us, so there's no sense in redshirting him anyways.
