I think that's exactly it. I don't rate Ayew's ability as a player, (as with everyone else with eyes), I don't even think he comes across well in interviews, but his attitude on the pitch is pretty great, in terms of work rate and the way he interacts with the other players.
It's just a matter of if it's worth having a Bard in your DnD party that contributes absolutely nothing to the team but adds a +1 to everyone else's rolls...
