Oh dear....
Please tell me you are intentionally missing the point.
The fact Stewart can't trap a ball doesn't make him a bad player, doomed to fail anywhere outside Scotland. Ally McCoist could trap a ball further than I can punt one but he still played in European competion and internationally.
Colin Hendry's positional sense and technique were all over the shop but he was a very effective player in his prime.
Some guys, such as Chris Mitchell, can have all the "skill" in the world. They are still crap.
This does not mean I think all "skillful" players are crap. Just the crap ones.
