He was even worse last year. Here's a post from the "Reborn Hank" thread in the Ottawa folder. I'm using it because I couldn't find his final stats.
That said, he does seem to be well-liked, he accepted his role just fine (right, Kevin Glenn?) and did contribute on special teams some. Maher started struggling on field goals right around the time DeMarco got injured in 2014 and I've always wondered if that wasn't because Maher worked well with DeMarco but not so much with his replacement.
