Tennessee has been running the same defense for several years. It’s pretty well suited to our players. The problem is, there is a ton of tape for good opposing coaches to look foe where we are weak. Bryce Drew and Avery Johnson essentially found the same weakness.
When you force us to make 1 switch with 5, and then don’t allow us to switch back (normally by isolating that side of the court) we are in by far our weakest set. You can’t expect our 1 to guard whatever big he just switched to, and Alexander is a step too slow to guard the 1 or 2. Basically you end up with either a quick look over the top to a big man being defended by a guard, or you end up with a shooter guarded by Alexander whose perimeter defense isn’t great. They either get another screen to open 3 or hit the pick and roll to open mid range.
Barnes adjusted in both games by moving our perimeter out, which gives us another half second for help to adjust to the ball as it comes inside. However what both Vandy and Bama did was then run the exact same offense again on our now collapsed defense. That resulted in essentially the same looks as there were in the first half, but they were late in the shot clock.
Basically, what we saw on both games were two very disciplined teams run an offensive set designed to exploit what is normally a very good defense. We’ve seen it in most games this year, but either the team didn’t have the talent or shooting to fully run it, or we played well enough on offense to stay ahead.
Last two games our offense has been the problem, the defense is working reasonably well. No defense in the world can do anything about bad or contested shots going in.
I would certainly defer to Barnes experience here, but I feel like if we would switch between zone and man a little more often, and run an easy 3/4 pressure it might keep opposing offenses out of rhythm since they are essentially running one play against our man defense. The zone/man switching will force them to play two very different offensive sets, and the 3/4 pressure will eat some shot clock.
Anyway...just my two cents.
