I'll be surprised if Cumbie leaves. Doesn't hurt to interview. But from what all I've heard, Sonny loves it here. He and his family love Fort Worth and the community of friends they've established. I think Cumbie is smart enough to realize that he's next in line here at TCU with all the recruits he's worked to bring in.
You have to think Meacham is a HC after this coming year...give Sonny one more year under Meacham to fine tune everything before he takes full reigns in 2017.
Texas is a hot mess and has shown zero signs of getting things turned around. Have another bad year next season, and Strong is gone, and Sonny might be too.
Also. If you're a rising OC, think how exciting it must be to pair your offensive game planning with a Gary Patterson defense.
