Your opponent can stop everything from money plays, to running the ball, to nano blitzes and F@G D, but the one thing ur opponent can't stop is user stick. Shutting down money plays is easy, cuz once ur opponent does it once or twice, u catch on and make adjustments to stop it. Same thing with running, nanos, and F@G D. once ur opponent sees it once or twice, he stops it, but he can't stop your user skills.
If you have pure stick at swatting the ball, then ur gunna piss a lot of ur opponents off, and they'll prolly quit against you. If you have pure stick at causing user fumbles, then they'll prolly try to adjust and get out of bounds when they catch or run the ball. Same thing goes with picks, they'll prolly end up running it up trhe gut everytime.
If you can find one thing ur good at, make a seperate account, and just lab it. Don't do anything but lab that one thing ur tryna do. If it's figurin out how to strip more effectively, then do it. Same thing goes with the User catch(not RC) and the route combos you have. It all comes down to a few things that'll decide the game, and user stick is one.
