I kind of agree with you... I don't think he was ever that good but he was a huge improvement over what we'd had up til then.
His workrate was immense but I think that was actually an issue in the end since he really should have been able to delegate scouting and the like to dedicated scouts and focus his energy on whats important for a manager.
His choice of player was wildly hit or miss but his first few seasons he found a few gems but he also picked up utter shite like Phil Roberts and laterly Tom fucking Hateley...

His supposed stubborness/attitude issues were meant to be the reason for the obvious rift that appeared in the team which ultimately comes down to man management for me since we went from a good tight squad to having a group that all wanted away for whatever reasons (Bain, Stewart, Hemmings, McGinn and Loy) and our fan favourite Harkins forced out of the club...
