I can only imagine a quiet seething. Earlier in the year, before his recent improvement, when we watched Anthony Mantha float, lend a hapless defensive effort now and again, a passive presence around the next for a guy wh's 6'5, 230 or whatever he weighs. When I saw that enigma-like performance, I would just wonder what his GM was thinking. I imagine he was seething. Quietly.
Now we know. Now we know that one Steve Yzerman had made up his mind to move Mantha and move him quickly. Contract or not, improvement of late or not, Yzerman has zero patience for talent that goes unrealized through lack of effort.
