We need accurate information here. The figure you used for Colandera is Passer rating and what you use for Chiles is QB rating. They're different things. Chiles's Passer rating is 134.He threw for 3,459 yd's (14th in the country), 23 TD's, 9 Int. and yes, he can run. He had a 149.5 QB rating.
(Chiles threw for 1,392 and had a 66.9 QB rating)
The only issue some people will have, is that he's only 6 ft tall. Not a big issue for me.
I believe he would be a better QB at NU than Minchey would. I would definitely take him over Chiles.
I would take both. The guy who loses out can be converted to receiver and then you have a lot of room in the playbook for some trickery.
