The Sum of the Parts I think the point that's being missed is - what is the actual objective here?
If it's to get to the Premier League and then to have a wholesale change of players, using PL-level budgets, then the age of the striker concerned is utterly irrelevant. Sa or Kermorgant would both be finished here at the point of promotion - who cares how old they are?
McDermott also knows the importance of team spirit and togetherness in the dressing room - he was there and heavily involved in the 106-point team, and he fluked a promotion in 2012with a squad that wasn't up to the job but got there almost entirely on team spirit and determination.
If he wants to get rid of someone who doesn't fit into the "togetherness and team spirit" he's trying to build, and replace him with someone else plus a pot of cash, fair play to him.
One of the most critical things in winning promotion isn't the quality of the individual players - it's their fit together in building a team. Sa might be the better individual, but if he fits into the team as a whole less-well than Kermorgant does then why retain him?
I agree with most of this post but how exactly do you fluke 15 wins in 17 games, conceding just 10 goals?
