Disagree.It's a myth that his forehand is bad, it's just ugly. They mistake it landing short sometimes for sucking but it has tremendous spin and the best angles in the game.
You're under-estimating it a bit. Spin, placement, angles are really good it's just not a top 10 forehand. Agree that he should use the flatter drive more against the top guys.Disagree.
Gasquet's forehands are 80% loopy forehands that don't do anything, 10% flat bombs that are great, and 10% shanks. If Gasquet had one of the 20 best forehands in the game, he'd be top 5 consistently because of how great his backhand is and because he could play such an all court game.
