Im sure he meant 3rd ranked junior. Ranoic has got to be the number 1 ranked player in all of Canada and these guys are not even close.
I dont see why you wont be able to get on a tennis team. A full scholarship (in the US) anyway is very unlikely. A partial at a scholarship at a lower division is very doable.
Obviously you already know alot of guys dont like your forehand technique. But i didnt see where it really caused to problems. If you're looking for a place to improve id like to see you use more legs to body energy to explode through your shots. Right now i see alot of arm work being done.
How tall are you. you look fairly short in the video but i couldnt tell for sure. I guessed about 5'9?
