In football, since building W's is important, I like the idea of playing a "name" school that is still beatable. So, I like the Ga. Tech series and the Okla. St. series in the past. And why I didn't like the West Virginia series. We have enough probable losses playing in the SEC - why add another one? So, I would probably pick Virginia or Iowa State or Michigan State.
Basketball is more forgiving, so I'd schedule as tough as I can - North Carolina.
Baseball... Don't follow baseball so much, so I'd want someone who has name recognition like Miami or Florida State.
