I looked a few match this week-end and when player are on court without hawk-eye they, it seem to play on their nerve a lot. It's bad for them but i think us viewer have some good moment watching this. Monfils was very **** off after every line judge for a big part of the match he played this week-end. What do you guy think about that? I think it is very nice to see the replay but it is also fun to see the player deal with what they think as bad call i really don't know which i prefer.
