Eh, sometimes. Calhoun had a tendency to not care about going over the line...or he forgot about the line altogether. Either way, he would toe it as well.
I'm reminded of a St. Johns game at Gampel in the mid '00s. I had the opportunity to sit right behind the St. Johns bench for a game that, while they pulled away in the end, UConn did not play particularly well.
It was one of those instances where the room goes silent just before one raises their voice, Calhoun yelled across the floor at Jeff Adrien to, "Catch the fv<king ball!!" The ref literally shrugged and T'ed Calhoun up, as if it was his only option (it was. Roughly 10,000 people heard it).
I really don't think Calhoun was being tactical in that situation.
