In no way am I indicating that Georgia is a good team (or even average), but Wofford is a good program. They've been to the tourney five times in the last 11 seasons and even beat Seton Hall in the 2019 tourney before a close 6 point loss to Kentucky.
While Wofford is a team a good Power 5 program should beat most nights, I'm not surprised for a second that they beat Georgia. I actually would have been more surprised if Georgia won.
