Retain as starters - where they are younger, I'd also offer longer term contracts with clauses:
Coleman
Ogie
Hutton
Masterson
J. Williams
Andrews
Turner
(Hawkins - maybe not starting, but definitely in the squad to rotate and support Andrews development)
I would make Connor Masterson club captain.
There's a nucleus there of a good L2 team, there.
I also would be very hasty to move away from Hawkins just yet - he offers versatility and about our only moderate offensive threat until proven otherwise.
Anything else, I'm indifferent at this stage. If Malone is committed to being here, he's a no brainer to keep too but I have my doubts.
Lapslie? He has teased and hinted, but there's just not been enough product. I would allow him to leave on a free as I believe his contract is up.
In my opinion, we need two major/key additions next year. A powerful, pacey striker (still!) and we really need a good No.8 to play alongside Coleman and support Williams properly. A leader with a voice, ideally - someone like Joe Pritchard from Accrington who is out of contract and has southern roots. Dieng isn't consistent enough for me,
On management, Clemence hasn't had enough time for me, not nearly. I do believe he can turn it around with some new faces. However, I'm not nearly as sold on Jackett / Hess, simply because not enough of the signings have hit. Ogie, Coleman, Hutton - all A grades, so that's in their favour. The lack finding a solution up top in 2 transfer windows means the seat should be feeling a bit warmer. They have to nail it this summer.
