West Virginia improved dramatically in 2014, and the defense should again be a strength. But the offense could make the difference between top 40 and top 60 (and between whether head coach Dana Holgorsen's seat is lukewarm or hot).
Charlie Strong spent his first year as Texas' head man cleaning house and building the foundation for an awesome defense, but until some significant, sustained questions are answered at QB and OL, the Longhorns will be limited.
In terms of injuries, turnovers, and a late peak, just about everything broke right for TCU, and that might be hard to replicate, but the Frogs will have an excellent shot at their eighth 10-win season in Gary Patterson's 11-year tenure.
If David Beaty can bring top-40 recruiting and solid organization to Lawrence, he could maybe eventually thrive, but with almost a complete reset on the first string, immediate success is a long shot, to put it kindly.
