I doubt they do. Herbert almost came out this year, but decided to get more ready for the NFL, he's not going to turn it down twice. Tua went to Alabama, and those guys have a strong track record of coming out, so I suspect he will declare also. The only one that might stay is Georgia's Jake Fromm, but Georgia always has a lot of talent, and I think he's planning to declare as well. I hope he declares, because he's my top choice for our offense.
