I dunno if putting umpires under more pressure is a great idea, sometimes they can be like players, having good series then having some bad form. You wouldn't want someone chastised and reprimanded after they'd had a bucknor if they're usually pretty good.
I thought reviews were a pretty good idea and on the whole, nicks and grassed catches have been cleaned up, but still big holes in how LBWs are handled..
They keep showing it and with good cause because it really was quite a poor call.
not sure about whether teams should confer over referrals, I think it's ok to get a second opinion, it's more about whether to use a referral so early, also, I think it's the captains call, you're going to kinda force the captains hand with field positions, he can hardly judge an LBW from deep square leg. Also, if the TV umpire is going to use a multiple of angles to judge the call, why can't the team confer with other players to get an all round picture?
