I'm a Spur fan too but I think we need to accept it's harder to fill a 53 man football roster with Spur grade players than is possible. Football is nasty and violent to it's core, basketball...well have you ever seen basketball players fight?
I would have no problem with Cogs coming back, but ONLY if he comes back and serves a Back-up roll, and is only used in case of injury to any of the current starters.
I just think it would be a media circus at a time when the team (and the country) is just starting to focus on how good this team might become. Don't rock the boat, even if it would give us more depth. I'd rather go down because we were depleted than because we were distracted.
