Great advice and probably a truism in all things...focus on a few things and master them. A jack of all trades isn't usually very good at any of the trades.

My brother was an outstanding wrestler. I think he knew three moves. An ankle pick, a simple stand-up, and a "cheap tilt." I'm sure his opponents and coaches knew exactly what was coming, but he had these moves mastered and didn't need much more.

Also, having the stamina to last the entire period can make a winner out of a less-skilled wrestler. A lot of matches are lost in the third period because a kid is gassed. If I coached, I'd have my kids jog for at least a half hour every single practice. We did that with a middle school-aged football team one year and they ended up winning their games in the fourth quarter simply because they still had the wind to run.
