He was a special, special talent.
I won't sugar coat it because for a lot of the Greig years he was in the doldrums the same as the rest of us, but then he'd come up with that special performance.
The 1981, SC final replay for instance.
I can't remember the exact timeline, but when Jock Wallace came back in Nov 83, he took one look at Coop and said I'm giving you a month to shed a stone in weight.
Coop got rid of the weight in half the time. He took to running round Strathclyde Park, wearing black bin bags under his training gear.
Sometimes, certain people can get more out of you than others.
Then there were the goals.
The 'thwack' when the ball hit the net from his free kick v Dolly in the 87 LC final, will stay with me forever.
