Athanasiou got a broken jaw, couldn't eat solid food for weeks, lost almost 20 lbs., AND missed more games than Mantha. Yet he still managed to work hard every game once he returned. Being injured might excuse the results, but not the lack of effort.
I don't see why people feel the need to constantly make excuses for the Mantha. He was used to streamrolling weaker competition in Juniors, and he learned bad habits, and hasn't unlearned them yet. It doesn't doom him to a career of mediocrity, but he doesn't get a free pass from criticism because he was drafted high and people like the fact that he's big.
To date, Mantha has been soft, lazy, and moderately disappointing.
Some would even say "very, very......"
