I agree with you, we've been poor in dishing out ill advised contacts in the past to entice players to Everton, however:
He's already under contract.
We're already paying him.
He can play a handful of games with no additional financial burden on Everton.
He might perform and earn an additional 20 games (and maybe even potential new deal - a long shot)
He might perform to a standard that doesn't convince Everton, but another club may take him on loan in January reducing our wage spend.
If we don't play him (at all, as you and others are advocating) it's almost certain we're stuck with him and his wages until he walks out next May.
It makes zero sense. Get him fit, get him on the pitch and see what happens.
