BTW, I meant to raise this earlier and forgot (and apologies if somebody has already brought it up), but has anybody heard about this?
Umpires to get video help on lbw decisions in Super Series
Sounds like they are going to use technology (in the sense of replays, at least) to help resolve LBW decisions during the Super Series - it'll be refererred to by the umpires when there's some doubt as to where the ball has pitched, and whether it was hit (as in, edged onto the pad).
I've never been sure about replays being used for LBWs in general, largely because of the time equation - even though I think it would lead to better accuracy (I'm dead against Hawkeye being used because I'm not convinced it's more accurate). The biggest problem with it is that some of the most shocking decisions occur when an umpire has little hesitation - and this of course won't fix those, 'cause they won't be referred. And if they're ALL referred, there's a very significant time trade-off to be had - player conditions would need to be changed.
I'm generally more absolutely in favor of using it for contentious edges (as in, was it the glove, the shirt, the bat hitting the pad, etc), and actual bat-pad catch appeals that umpires aren't completely certain on.
Either way, it'll be interesting to see what happens...
