1. He talked about a drill he did in college where he'd put his left foot against a wall and take an "air" swing, concentrating on hitting his left knee against that wall to initiate the downswing. This helped him get his weight forward and reminded him to start the downswing from the bottom up.
2. He specifically talked about the importance of keeping the arms in front of you and doing this by having correct elbow placement (basically, they should always point to the ground). It reminded me of the thread on the elbow thread on this site.
3. He said, unless your swing needs a major overhaul, you should get better after just 1 lesson with a pro. If you get worse after trying to implement changes from 1 lesson, you should dump the instructor. It was nice to hear a former pro say that on TV (as many of you know, 5SK guys say this all the time).
Most of the Golf Channel teaching shows usually don't grab my attention like this one did...
