Good wrestlers do have slumps. All good athletes have instances where they did not perform perfectly. For a wrestler, it may be a match they lost or won. You may be a good wrestler but have a slump and fail to dominate a tourney or match that you should have. Or you may get beat by another wrestler close to your ability because of a bad match or slump.

All athletes have had a slump at some point in their career. Good quarterbacks have 2 or 3 INT games, good hitters have 0-4 games, good golfers have bad rounds, and all athletes in all sports slump at some point!

The real question of greatness resides in your ability to overcome a slump, win when your not at your best, and put in the hard work and mental preparation to avoid another slump.
