There's absolutely no doubt that RM is a good keeper, in particular shot stopping. However, his distribution from feet is really poor - even on Wednesday he very nearly cost us due to his kicking. But he made up for it with his save from Vigurs (I think it was him) shortly after that. He can be caught out at his posts a lot too, but I do concede that keepers get more criticism than most due to the importance of the position (and its specialism).
If Rocky could improve his ability at feet, he'd not be at Hibs, he'd be down south for a very big fee - no doubt about it.
