It has very little to do how many decisions are getting overturned. DRS/HE has just caused a shift in how the LBW rule is applied and "padding away". Umpires just give more LBWs to spinners now because they know if they don't DRS will overturn it.Yeah, but I still think the no. of decisions getting overturned in favor of batsmen isn't too few; and especially given that we are considering it solely on home, definitely not all lbws needed to be plum and the bowlers had an advantage for close calls. Probably umpires are more open for lbws now, but home umpires giving advantage to home bowlers should also be accounted for imo.
Finger spinners get almost twice as many LBWs as a total percentage of their mode of wicket taking post DRS. It's went from roughly 11% to 21%
That's not opinion. That's fact.
