Those four pictured are, of course, QB Bryce Petty, MLB Bryce Hager, WR Antwan Goodley, and P Spencer Roth. They will join Big 12 stars like DT Malcom Brown (Texas), WR Kevin White (WVU), CB Kevin White (TCU), TE E.J. Bibbs (ISU) and a host of others (full list here) the week after next, February 17-23.
I think most of us expected that Goodley and Petty would go, for sure, but to see Hager and Roth join them there is particularly rewarding. Had Spencer Drango and Shawn Oakman decided to declare early, they would have joined the other four in receiving invites, I'm sure, but we get the benefit of another year with them around, instead. I'll take that.
