Both Sutcliffe and Sheridan probably rank somewhere between 15 - 25 in the pecking order. Not world beaters and never will be.
There is a bit of a youth obsession on this board, but for me I think we would have got more out of Sheridan over the next 5-10 years than either Giro or Crowden. But people like to attach themselves more to potential than ability. For me, I would have held on to him. I'd even have held on to Sheridan ahead of say Ballantyne who got another year (and yes, I know they don't play the same position).
Sutcliffe I think ranked slightly below that and probably was a worthy delisting.
