I don't think the important discussion is what Coach O'Connor looks for in recruiting. He is looking for a top tier talent/athlete.
Where I would think the rubber meets the road is with those coaching staffs in programs ranking in maybe the 50-125 range. Multi-sport athletes with upside when playing year round for the first time can make a big difference for them.
Among the obstacles for those coaches and the players include how do they find them or get found, how do they recognize them if they find them, and how does all of that get done within more limited recruiting budgets for their programs as contrasted with UVA, for instance.
Multi-sport athletes, especially football, are not going to be seen during the period from August to December. Very few will be found during the HS season because of the demands on a college staff during a 56 game schedule, weather for HS baseball and a short HS season.
If these players go to the top showcases/travel competition during the Summer, only the top guys(a UVA type) will normally stand out. Those with athleticism, solid but undeveloped talent with big upside won't be very obvious to coaches in many situations.
In essence, I think it is much easier to talk about than to do for those college coaches who are not at the UVA level, especially in resources. It is equally challenging in the current showcase/travel team landscape for multi-sport HS athletes who are not at or near the talent level to be recruited to UVA.
