Disagree, those aren't reasons one bit. Maybe Carroll is occupied. Who knows? But I'll wait to get excited when I see UM confirm it accepted the LOI.

2 reasons. 1. He is out of state so they have to send the LOI and that may take a little time 2. He is a 2013 commit so since its after NSD a regular verbal commit really won't do it.
