One of the things that has to be considered is how Senyshyn has been managed in Providence. Despite the intriguing stats and unbelievable size, speed and skill package in his draft year, Senyshyn was by far the rawest prospect taken in the 1st round. If I recall correctly, by the time he got to Providence, JAy Leach realized that if he was going to make it in the NHL (at least as a Bruin) he would need to redefine his game to focus on forechecking and crashing the net. He has played primarily a checking role in Providence with very little PP time until just before the COVID pause. Anthony at the Bruins Network reported that Senysyhyn was often the best player on the ice for both teams due to his hyper-aggressive forecheck. Now that is something the Bruins missed this postseason.
For reference, here is Leach's postseason recap on both Seny and Zboril.

Senyshyn's competition for the 4RW are essentially Wags and Kuhlman. Those are the guys he has to beat. Based on the poor performance of the 4th line last year, I would imagine the job is totally up for grabs.
Now, some of you have mentioned Seny might be "gifted" a chance higher up the depth chart. Whether you like it or not, Senyshyn has paid his dues in the A. So, if he ends up getting a look alongside Bergeron, Krejci or Coyle...it's because he has earned the look. The question is whether he can keep the job.
While I look forward to seeing more of Kase, until he produces on the scoreboard, he is entirely replaceable. I wouldn't be surprised to see Kase continue to struggle in that regards...or god forbid he get his clock cleaned for the 20th time...that might be the type of opportunity Seny needs to get an extended look.
I wouldn't bet my mortgage on Seny playing more than 20 games in Boston this year...but if he does, I think he is the type of unique player who could thrive once he figures it all out.
