Oh, definitely. I did my warmup jogging upstairs from the smaller courts and saw some kids playing, so after I got my reactive work done I just kinda went, "hmmmm.... I wonder how high on the net I can touch now...." Wasn't really expecting to touch rim. Oh, and I confirmed (at least kinda close) the rim was at 10'. Tried doing it on the main courts after the basketball game was over. At first I didn't get it and I wondered why, so I just eyeballed it with my hand reaching towards the net, went to the one I had done it on earlier. Looked exactly the same. Couldn't get rim at first there either but then I realized I had finished squats about an hour earlier. Tried a couple more times and got it then, but only once. Still felt way cool.
Increased leg power ftw indeed.
