That's got to be up in the air till the full extent of his leg break/recovery is known. If there's no lasting damage he may be a decent signing as player/coach. Others will be aghast at the thought but I was impressed with his last three performances as a player and it's just my gut feeling based only on what I've heard that he'll make a very good coach.
Re Adams, Lovell & Shields being "a waste of money", I doubt many can argue with that. The Lovell thing's been talked to death, fine initially but extending past January the real crime. Buchanan was out to start with and the partnership really should have worked better. When it was clear Lovell had fitness problems then it was time to say goodbye.
With Adams imo the mistake was the opposite. Why take a guy who's not match fit on a short loan if we didn't have a first option on a deal to the end of the year. From what I remember if Jeffries hadn't jumped ship Adams was going to Queens straight away in January.
As for Shields sorry, I've really no idea why he was here.
