Rice, quit apologizing for being a freshman and listen to the advice of others that know what they are talking about. Against any opponent that is any good your head-and-arm is not going to work. If you want to get better then stop using it and work on setting up shots to get takedowns. A good set up combined with a good shot will usually work for you. But obviously some guys will still be able to prevent your takedown and that is why you drill re-shots.
And I agree with Jhris, the move is called TRASH.
