The expression 'lack of pace' just doesn't encapsulate his immobility.
He wasn't actually that slow or immobile when he first arrived. He was also, amazingly, thin. But who the feck cares about his lack of pace? He didn't NEED pace. That's different to the likes of Josemi, who needed it but didn't have it. Molby didn't need pace. Like God doesn't need friends in high places. He controlled the game. He could probably control a game even now, Watch him in a legends game - he can actually think, see and pass. It's really handy.
