StrandedSimmopsSnowflake Royal Maybe. He kinda made it - performed well when he came in. Then crashed after, especially when we switched to Clarke. I'd take that from one of our current benchwarmers.
He never made it at all
Scott Davies aswell is another
It doesn't hurt to admit you are wrong for once Ian
Davies was much more to do with his well documented gambling issues than getting a chance too early. Campbell did his cruciate a few months after his only sub appearance and never recovered enough to play professionally again. Castle played 11 mins of the same Campbell did (also as sub) so pushing it a little bit to say that ruined his career - his really rather shocking spells on loan in non-league did that.
Nicholas Bignall may be an option but I don't think getting a chance harms players more getting into the squad, being involved sparingly and then disappearing back to the youth i.e. it is almost better to be on the bench and not get on that get 10 mins here, 5 there before being stuck away from the squad once injuries clear up.
There’s also the element of, it may not have been that they got the chance too soon, but perhaps some were never good enough and shouldn’t have got the chance to begin with.
