Scoring is way up league wide, so having 6 more points while no longer playing in a Trotz system seems about right to me. I honestly don't watch a ton of Isles hockey, but I tuned in for a few games and Mayfield was one of the players I was most interested in watching, and he definitely looks like he has lost a step defensively. Very small sample size, so could have been a few bad games or he was playing dinged up, but I think his defensive metrics were the worst they have been since Capuano was coach. What worries me most is that a lot of Isles fans don't want mayfield back if it is longer than 2 years - that tells me they are also pretty worried about his decline as well.
For the record, I said 2-3 years would be great, but like I said earlier, I don't believe he signs for less than 4x4 (remember, he has been underpayed for a long time and never got that big contract - this is his last chance).
