I don't watch basketball much, but when you see a blowout in football, the winning team normally starts running the ball every play in the 2nd half and starts substituting backups liberally. They might keep running the normal offense if the backups are in. Sometimes they wait until the 4th quarter to do all that. It depends on if the losing team is still scoring or not.
In basketball, I would think momentum means a lot, but with only 7 points, I really doubt the losing team ever had any at all.
