I guess how I'd answer that is that every recruit is a risk and the farther down the pecking order you get from being able to pick and choose pretty much whomever you want, the greater the risk becomes.
Within that, there's a range of risks.
MacIntyre doesn't seem to think that taking many character or academic risks is a good bet to make. He's got what he's looking for and then gets the best players he can within that. Some academic and character risks from him, but it seems a lot less than the norm. His risks are more in the realm of taking guys who aren't as far along in their physical or football development as you'd like, but have potential. Or risks in the realm of taking someone who brings a certain attitude to the team being trusted to outwork people to be successful as a player in the Pac-12.
Hawkins, by contrast, was willing to take huge risks on talent/character (talent that got rated highly but, in the end, most top programs shied away from) and then balance out the likely problems on attrition with guys who couldn't play but would be great citizens and scholars. When too many of the risk guys washed out, we got what we saw.
Embree (with EB) wanted guys with NFL dreams and the requisite physical tools and were willing to risk just about anything to get those guys into the program. Admissions didn't play ball on a lot of targets.
My belief is that MacIntyre's approach is the one most likely to work at the CU of today. It will wash out if he doesn't achieve better on-field results in order to keep being able to systematically upgrade talent within the overall parameters, but it's not going to risk attrition and bad attitudes blowing up the roster's talent like we had under Hawkins. And it's an approach that the university will actually support, unlike Embree's which was trying to fit a square peg in a round hole with the way things are at CU.
