Again per the Edge stats, yes Poitras is slow. Which is no surprise. But so is Geekie. Glacial. One of the slowest forwards in the league. Doesn't seem to be holding him back, but it is what it is. Lattieri is slow too. Even Jones is actually in the bottom half for top speed. Would never call him a laggard, but appearances can be deceiving.
The only Bruins forwards who are in the top 50% of the league for pace are Pasta, Zacha, Beecher, Kastelic and Koepke. Probably Lysell too if he actually saw some decent time in Boston. But that's it.
