Merrill missed the first half of the season due to a cracked vertebrae and played his first game for Michigan in January. He was in the middle of things for the eighth-place Wolverines’ late season nine-game unbeaten streak that ended in the CCHA conference championship game. In 21 games he scored 2 goals (both on the power play) and had 9 assists; finishing +3 with 14 penalty minutes.
Merrill is a solid two-way defender with outstanding poise and hockey smarts. He skates very well, shows no fear in rushing the puck up the ice and can quarterback a power play with his great distribution skills and shot. Since he has not played a full season of hockey since his freshman campaign at Michigan, he is still a little raw. Still, he has risen to the occasion and makes his team better whenever he’s on the ice.
For the second half of the 2013-14 season, Merrill was arguably New Jersey's best defenseman. Now with management's commitment to play their young blueliners, look for Merrill to establish himself in the team's top-four.
