Your arguments ridiculous. You are arguing it's better to have nothing than literally anything. For someone that actually does spend time in the youth team thread it's a bit of a mystery why you bother if you actually think there's no point to any of them being there ahead of no one. It's a bit odd to say Campbell, Welch and King are fair to pick as needs must and then draw the line at objectively better players than them. If youre saying they wouldn't play anyway so what's the point then fine, but we might as well have named a 4 man bench in that case because them 3 and Aznou wouldn't get a game and aren't ready either.
Graham might not be PL ready, he may not even be championship ready but he's certainly better than an empty seat on the bench. Tamen may one day have a future here, he's arguably better than them 2 on the bench already, it's better for him to sit on the bench than Welch or Campbell.
Olayiwola or Foster aren't ready but at least you could give them a go on the bench for the sake of it than nothing just for match day experience.
