Wait what where'd you read that ??
With zone starts of 25%O and 35%D, he had a CA60Reltm of -8.6 (Best on the team), which basically means when he was on the ice, the team allowed fewer shots against.
Heck, even the year before he had a -9.7 CA60Reltm (Best on the team again). This doesn't mean he is a superstar
, but it means he outperformed his usage on the 4th line. I'd say he's an above average 4th line player. He reminds me of B.Boyle when he dominated the 4th lien. But when B.Boyle was put to the 3rd line, he didn't perform to the same level (to the level of a good 3rd liner). If he comes to Toronto, I expect him to be strictly on the 4th line.
He's an odd player for sure, but if the Leafs are interested in Martin that has to mean he's at least somewhat attractive possession-wise.
