For play style attricutes, I guess he was similar to the older option QBs, but with more passing ability. You are right though, he was an overachiever. He played beyond his measurables, at least imo. 6'0, 190lbs. He still had above average physical ability (maybe not arm strength), but mainly used his wits, will and hustle to succeed. Very good mentally (reading D and such), great leader....stuff that we don't have rating slots for, lol!
By his Senior yr, he actually had decent speed. Nothing like today's QBs though.
He was just really balanced, and could do a bit of everything (mid level or above). Fairly elusive runner (again, no speed like Eric Crouch or any recent dual-threat players), no power run or stiff arm, maybe more vision skilled than juke skills, but he had some of those too...kinda slippery, but not a trucker. Evasive in the pocket. Took a pounding due to all the running, so he was banged up quite a bit. Very tough though.
I'd say maybe a poor man's Groethe (sp?) - QB from South Florida a while back (really at a loss for comparison). Not a big arm, but fairly accurate and enough to go deep if he has to. More of a mobile, roll-out style passer, finding the angles and stuff, rather than drop back and sling it, but still mobile within the pocket. I found it noteworthy he broke the school passing record, although he was in basically an Option Offense, and splitting time a lot...granted the numbers were low, but still.
I have the 94-95 v Duke game at home, I'll check on that and give you a better update (although I think Mike Thomas got a lot of time that game, maybe injury).
I did find this quote from FSUs DC, from the Orlando Sentinel (although I think it's stretching it slightly...but I'm not a legendary coach, so what do I know!):
Defensive coordinator Mickey Andrews, fresh from a film session evaluating North Carolina's option attack, put him on a par with Nebraska quarterback Tommy Frazier.
''He makes a lot of good decisions and very few bad plays,'' Andrews said.
So...Maybe a more accurate, tighter spiral throwing, less 'diesel', less powerful of a runner than T. Frazier. Not sure how fast Tommy was, but maybe that would be close (I'm guessing Tommy wasn't a speedster - but a great runner nonetheless, he was big and strong, I know that much!).
here's another link with some cool comments...go to the 'best heel ever' section (from Andrew Jones @ InsideCarolina 2002).

He describes the 'most underrated Tar Heel ever' as,
He was a classic college quarterback, one who could do many things well, but few things great, except his leadership.
For Madden DNA...maybe a really stripped down Steve Young? Or a young mobile Rich Gannon? I know he wasn't as good as Tommy Frazier, and lord not Steve Young, but similar styles possibly.
