The number of games played in lower leagues and a players age does not determine ability to play at top end championship level. Look at Sessignon aged 17.
Brooks has had 23 appearances mostly in the championship is the same age and on a completely different level to Reed in terms of skill, ability, pace and goal threat. In three years time he'll be plying his trade in the premiership. Whiteman 1 year older has played 64 games all in league 1. Thats his level at the moment and its questionable in 2 more years whether he has the ability to move up to the championship.
Reed has over 70 appearances split between league 1 and 2, no appearances in the championship. How can the club justify a new 3 year contract in the championship based on that? It doesn't make sense. I wish him well but he doesn't fit the profile and all indications are he will be moved on.
Blackman, a goalkeeper with a premiership club, like Brooks has tremendous potential for his age. We won't be able to afford him but a 1 year extension to his loan would be very welcome.
