I get that goal/assist stats are important, but there is far more depth to football than just that.
Naismith might score a lot of goals compared to Lennon, but you have to look at the impact on the players around him. It's a team game. I mentioned Coleman as his form improved noticeably when Lennon arrived (Seamus said as much himself), because he had an intelligent footballer ahead of him who had the presence of mind and physical fitness to cover for him at any point during the 90 minutes. For a team like us, having wide men who work well with their fullback is utterly key.
