Barton's time with Glasgow Rangers came to an end last week.
Barton was one of Mark Warburton's marquee signings during the summer as the Gers boss attempted to build a squad capable of hitting the ground running following their promotion to the Scottish Premiership.
However, the 34-year-old spent a large portion of his spell with the club suspended after a training ground altercation that came in the wake of Rangers' defeat to Celtic in September.
And the saga surrounding his future finally came to an end last week as the Light Blues agreed a settlement with the player that saw his contract torn up.
But McCoist appears to have some sympathy for Barton, and suggested that his personality may have elicited a different response from his teammates had he played for the side at a different time.

"We had big names, guys you wanted to stand beside, go for a pint with it. We had fall outs but it was sorted and we moved on," he said, as reported by the Evening Times.
"I don't know Joey Barton at all. But I just think perhaps his character wasn't suited to that dressing room. I might be wrong because like I say I don't know the lad at all, that's just my observation.
"I played with guys who had real personalities and I don't think that's the case in football these days."
The incident would have perhaps put Warburton in a difficult position had it created a divide between Barton and the rest of the team.
While McCoist feels that Barton's character could have been beneficial, Warburton may have been wary of bringing him back into the fold if his return from exile was going to rock the boat too much, especially as by the time that Barton potentially won his teammates back round, he would probably be well into the twilight of his career anyway.
