While that appears to simply be a coach standing up for his players, Kevin Bieksa wasn't too happy about it, and during Game 3 in Edmonton, the former NHL star let the Dallas Stars know what he thought about their comments.
Essentially, Bieksa is calling Hintz soft for acting like he was seriously hurt before being back on the ice, but he would eventually miss Game 3 due to that injury, so Bieksa's comments are a little bit off as a result.
At the end of the day, the comments from all sides over this situation have only stoked the fire of what is already a very fiery, intense Western Conference rivalry between these two teams, and if Hintz is back in Game 4, we can definitely expect more physicality as a result.
