I love Martin. You are expecting more than should be expected of him. Jamar's 'J curve' wasn't as steep as you would like Martin's to be - it's unfair on Stefan.
If he wants a long term gig, he knows (as he intimated in that article) that he has to be versatile and develop a presence in the forward line.
Jamar is our first ruck, he is taking our midfield on a armchair ride to the top 4 if they want to go and I think the club will move Jamar forward more but he will still be in the ruck predominantly, especially against the better teams.
