The problem is that NU rarely gets guards like the type you describe. McIntosh was able to get in the lane because he has areally strong dribble with his off-hand and he developed that teardrop shot very well. Ryan is a bigger version and I think he will ultimately be a better three-point shooter than McIntosh. I think it would be a mistake not to pursue Ryan.
I agree that NU would benefit from Ryan's shooting, but, with my usual caveat, we really need a PG who can penetrate and got shots at the rim. That wasn't Mac, as much as I loved him. His 2-pt shooting went down over his career and his 3-point shooting was OK but never great.
