Ha! Yes, I used to play football and run track. I was a long jumper and sprinter, and in college football I was primarily a cornerback and punt returner. I noticed in another thread you played football too. What position(s)?
Keep working hard and I'm sure you'll be able to lean on your swing in future tournament golf.
Half the battle (for me at least) is the mental side and having the confidence in pulling off a shot under tournament conditions and pressure. And then if something goes astray - being able to pick yourself up - brush yourself off - and get back into the match. Going back to the wheel house and doing what you do best to complete the round.
This was the biggest issue. It is quite humbling, actually. I knew what I needed to do with my swing, but I was very scared to commit to a hip slide and commit to trying to get shaft lean with the club for fear of hitting a hosel rocket or a fat shot. I hit the range for 2 hours after the first round and before the next morning's round, and hit the ball better the next day. But again when I was put into a tough shot situation, I went back to casting at the ball to some extent. It does help me understand just how much more practice I need in order to be able to lean on the swing when I really need it.
It also gives me an appreciation for how well the pros play on pro-level courses.
