don't trash talk yourself. have confidence. even the best players miss shots, believ you'll make every shot you take. (don't let that state of mind trick you into forcing bad shots) and when you miss a shot or make a shot, never let that get to yo...
I can do it fine and i'm 5 pounds lighter at the same height. Just generate a lot of spin of the board and when you drive press the ball and hold it like a running back does.
do sprints on the track, run bleachers, do plyometrics and do them all at full speed and push yourself. Don't settle for just a few reps, when your dead tired and really cannot go anymore, thats when you keep going even more.
You gotta consider Melo for MVP, I also like Durant but his team isnt good enough right now... also you always gotta put kobe, lebron, nash up there as well(maybe wade, who should of won it last year imo). But for me its way to early to tell.
