Or he didn't want them to have time to set up an offensive play? It can be that simple sometimes...But I know it's bash on Pike time so go at it...
If a set full-court UMass offensive play with 4.8 seconds left is even the slightest concern for a set Rutgers defense (the foundation of our team) then that's a bigger issue.
This wasn't Duke or Gonzaga setting up a play.
I don't mind not calling a timeout - everyone should have been up and pressuring the ball regardless and not let them get a free run up the court.
But I really hope Pike wasn't thinking "we were worried UMass could set up a full-court offensive play with 4.8 seconds".
