It's a difficult one this, others will say it's not. However my impression is that PB very much rates both Jack and Jason hence why he's kept on . I reckon he will continue to see how they develope this season in the new under 21 team, which if other teams play "stronger" negates the need for loaning them out . Maybe just maybe he feels that mentally he ( Jason mainly ) be a little too soft just at the moment for a promotion. My point being, which can happen, if you promote someone too early and say they go 5 or 6 matches without scoring for the first team , this could actually affect the final stages of the development of the players. Just my take, but I think that PB is very proud of our youth development, when you look at Bentley, Smith, Payne, Williams and Bridge, that ain't bad is it !
