after watching the Safin-Tursunov horror movie today I think we really need a technology to challenge foot faults, some sort of sensor on the lines or hawk-eye like stuff, it certainly would prevent such outcomes, agree?
not bad, agree!
Scary thing with footfault is that it only calls the line umpire, and chair umpire has no real control over that. I know not one foot fault that get overruled.
So you can imagine, one asshole line umpire can screw up matches with foot fault like he wants.
