I will probably get shot down for this:
I think this is a good thing for both Trott and the ECB. Not a good thing for the individual that it has happened - I wouldn't wish what Trott is going through on anyone, and I sincerely hope he is able to sort himself out.
What I mean is that it is good that it has happened now. Trott knows that he cannot go on within the England set-up, England now know that they cannot pick him, and can start planning for who will bat at 3 and start to build po their new batting order.
I have a feeling that over the years the ECB have chosen to turn a blind eye to player emotional problems, and keep on picking them and forcing them forwards to play whilst ignoring the symptoms.
I'm thinking of Tresco, Trotty, Yardy, Bopara, Monty and for different reasons Swann.
I think all of those have been picked to play because it suits Team England, rather than looking deeply at the player themselves and realising it's a disaster to pick them / take them on tour.
Don't get me wrong, I also feel it's beholden on the players themselves to be a bit stronger and say "look guys, don;t push me in to this - I really can't play right now" and that's something I don't think has happened when it should in the past.
