Sometimes a group is greater than the sum of its parts, you know?
That's why groups that look great on paper sometimes fail to grab, and a band full of otherwise 'nobodies' (hate to use that term, but I will for now) might take it much farther. Therefore, I might prefer a Rocky Boyd record to some Dexter Gordon sessions, just because the group was more 'on'.
One player may lag a bit behind others in skill, but if the music is in the aether and there's no slack - only effort, joy and intuition - the music will come through as raw as one hopes for.
