I would be surprised if he makes the team, but I agree that it is kind of a weird signing. The other one that confused me was when they signed the Hurricanes QB Rosier. Dude couldn't even keep a starting job at the college level. I'm assuming maybe they sign former Hurricanes as kind of a gentlemen's agreement to support the local college team with recruiting or something. "We have had X Number of our athletes sign with NFL teams, so you should come here to get your best shot at getting in the NFL."
They didn’t sign the QB. My take on that is they needed a QB for the weekend on short notice so they called a guy that wouldn’t require an airplane ticket.
