They've had a lot of success with big recruiting weekends after the season and that's the plan for the December visit weekend.
True, the gameday experience is a real plus if it's a good win but they have so much less time to spend with the visiting players, too, so it's a double-edged sword.
I don't like the risk of doing it on the weekend a top opponent visits. It's too risky, IMO, and not a big enough tradeoff in benefits if they win to risk the loss like last year vs. SC.
The recruits have responded very favorably to the big visit weekends during bowl prep and the coaches and players are really able to focus on them and spend time with them so as many as were okay with doing it on a non-gameday weekend will be there.
