I think this is probably the natural progression for that group of players, people such as Sawyers, Hurst, Kemar Roofe, Kayleden Brown, possibly Scott Allan too, lads who have been around for a while, are early 20's now but never really troubled the first team, i think they will go on loan / get released in the summer, drop down a level or two and try and work there way up.
Not saying you are written off at 20 / 21, far from it but with the likes of Thorne, Donovon Daniels, Abil Nadi, Berainho, Izzy Brown, all a couple of years youngers or same age being highly thought of and involved in first team squads the lads mentioned at the top probably need to go somewhere and play every week for a couple of years and go from there, it will do them good as short loan spells and reserve team football just isnt the same.
Hope it works out for all of them
