No disrespect to any poster but how, exactly do you, as a poster on a message board, know that a player is ready for 1st team action when their coach, his coaching team & the academy manager all think he's not?
Bear in mind, that coaching team will have seen him every day in training, will have seen him play in the games he's played in, be they 1st team, A team or on loan.
Its all very well saying, play them otherwise we'll never know if they are good enough, but, firstly, The coaching team should know if they are good enough or not & secondly, blooding youngsters is a really tricky thing to do. Play them too early & it can ruin their development, leave if too long & they may leave for game time.
Are Wasps getting to right? Not sure, but to say that Dai won't play youngsters is far too simplistic IMO.
