the kid is definitely a twig...super skinny apparently at around 160 pounds on a 6' 3" frame but he looked really poised with the puck, good skater and moved the puck well. His offensive upside looks limited but the same was thought about Myers who's situation is very similar to Zamula's. He looked a little shaky when playing vs. the Rangers but these are players several levels up so it's understandable.
The Flyers are deep with young dmen at the NHL with Provorov, Gost, Sanheim, Hagg, Myers, Morin so they can afford to take it very slow with him and give him time to develop. He gets added to their next crop of Hogberg, Kalynuk, Ginning and others that will work their way up and try to break the roster in 2-3 years.
Looks like a good low risk signing....
