Many games you seen this season?
I've seen about ten games this season, both when in the country and some, not all of the TV matches. In none of those games have either of the above impressed (taking a 'nice touch' isn't actually the criteria of an effective central midfielder). That view is further borne out by our mediocre league record as a team and poor goals and assist records for the pair (McKee has improved in the former but doubtless Raith weren't s***ting themselves about the threat of goals from midfield today). Looking at their track record as well - Forbes flattered to deceive IMO last season; McKee has stunk the place out for years.
So yeah, only if you're wanting central midfielders who can't stop the opposition from playing, don't create enough chances and don't score enough goals, then re-sign either of those two to have us huffing and puffing towards the coveted forty point mark again in twelve months time.
