IMHO the bouncer should still be legal, but I don't think we will see a bowler bowl one for a while, just because of what's happened. Hopefully whats happened to Phil Hughes will create a review of all cricket and where it's heading including protection. I personally think T20 needs to be looked at. I think the Dilscoop should be banned, I've thought for a while it won't long before a batsman, keeper or close fielder not there for that shot will be hurt. Also you see kids playing it which is very worrying, you could also put in there the reverse hit and slower ball bouncer, which puts the batsman in exactly the position Hughes was hit with the ball still in flight. Anyway just my thoughts, I'm often wrong.
Tonight I've been listening to radio 5, a replay of Hughes talking about his youth and playing cricket brought tears to my eyes.
