If you want the best depth for our Europa League matches, maybe.
If you want the best Oliver Skipp in three years, you go let him bed in and become a core contributor to a team from pre-season training at the age of 19.
There's no perfect, foolproof way to develop a player, but I do think one sin of the method of keeping young players on the fringes of the first team is that they calcify into their roles as background cameo players and don't really get to explore what they can be as senior professionals.
I'm a Harry Winks fan, but in some sense he's only ever become a rich man's version of the academy kid you bring on in the last half hour to play a simple, structured game.
I don't know if Skipp will become as quality and reliable of a player as Winks, but I think his game is more expansive than that of a ball recycler. If he wants to develop that it's better to be the looked-to number 8 in a bunch of roiling Champo games rather than the caretaker of a 4-0 lead against Dynamo Spellcheck.
