Actually he needs to swing more effectively, with more connects than near misses by making his punches more directly aimed instead of swinging too fast too often.

In other words, yes he needs to prepare for the debates more than he did for this one. This one is okay though because it may have just made Hillary overly confident, and in the next one he can deliver the knockout punch.

A much better, more nuanced way of saying what I was getting at. Kudos.

He could learn a lot from Newt. Newt just tells people they are wrong and proceeds to bombard them up with 15 bullet points. He knows how to disarm his adversaries -fast and furious. The classic example is when he took on Juan Williams for six minutes in 2012.
