But, seriously, playing hockey for Texas Tech isn't as hard to do as playing hockey for, say, University of North Dakota. It's not a varsity sport at TTU. They don't even play in the NCAA, but rather in Division 2 of the American Collegiate Hockey Association. So, while it is important to keep yourself in playing shape, it's unlikely that you will be "recruited" to play for TTU unless you contact the coach yourself and let him know that you are a hockey player who is interested in going to school there.
