In nfl pro 2014 app for iPhone how do I kick far?

Ok so the app nfl pro 2014 is fun and all but when I do field goals they don't go straight and when I kick off the don't go far

When you slide the ball down (for FG or punt) don't slide it all the way down cause then it will f*ck it up, then slide it back all the way to the top and it should go far
