You are correct. The Big 12 is a very good & tough conference. Add in the other major Texas schools (Rice, TCU, etc.) and this is a hot region for baseball. Not to mention San Jac & the other JUCO's.
That draft can hurt as well. If I recall properly, one year A&M had six pitchers drafted. Talk about wiping out your staff.
And then there is that wonderful scholarship allotment for baseball...
