I wouldn't say "give him credit", but we did sign Ward and Beck while he was the OC. So the QBs themselves have to see themselves as a fit with Dawson, and Dawson has to utilize Ward and Beck to the best of their abilities. So I'll give Dawson half-credit, though you are correct that Mario/Dennis were the actual in-person recruiters.
As for whether Emory was truly beloved by Dawson...let's not forget that we made a huge play for Mateer BEFORE the Pop Tarts Bowl. Yes, we got Beck AFTER, but I think that all the coaches knew we needed someone else to start over Emory even before the debacle in Orlando.
