Ah! I hate silent commit rumors!
That said, I don't think Dooley purposely tells the kids to keep it quiet. I just don't think he "suggests" they time & leak things in ways that Kiffin did (I think Kiffin liked to create drama & have timing to his commits). That's not what I think Dooley does. Dooley just keeps things quiet cause he's a businesslike man. The recruits, if nothing else, are implored to take their time, look around, see that UT is where they feel comfortable & excited about, so that when they do commit, they are 100% Orange.
JMO about the way he handles things.
