Because we're in that twilight area where the squad - especially depth - is too good for League One, but is it good enough for next season.
I agree this season is for getting the formation, tactics approach ironed out but equally at times we've ridden our luck a bit. Trott has been outstanding, but against better quality finishers we'd be punished. If we can start putting teams to the sword, then I think we'll stay up next season in the Champ. In terms of assessing which players are Champ quality, it's difficult to say atm.
