When they announced Trent Cull would be back with the Utica Comets for another season, that was probably 'it' for Palmu. The two were at loggerheads over ice-time for the entire time he was there.
The Comets didn't send him home. He chose to quit and go home. What did he expect when he was unable to simply keep up with the play? He was down on the ice more than he was on his skates. So, he got scratched.
When the season began he was in a group of players who were being jockeyed around in and and out of the lineup. The group was composed of:
Lind
Palmu
Gadjovich
Jasek
Carcone
Palmu played :
Game 2
Game 4
Game 7
Game 9
Game 10
Game 11
Game 13
Game 14
Game 15
Game 16
Game 17
Game 19
Game 20
Game 26
He was scratched Games 27 and 28. The last one being December 12/2018.The Comets played again on December 14th. Palmu was gone.
He had played in 14 of the Comets first 26 games. I think he got a false sense of security when he played games 13 -17 and then 19 & 20. Then he sat out the next 5 and I believe he felt he was being skronked. In reality he got that stretch of games due to a large number of injured forwards. The injured returned and he found himself scratched once again.
Truth was he was actually being rotated with the bunch for the first 9 games or so. At the end of his consecutive game stretch he proved to be the Comets last man up front. The rest passed him by. When he left Gadjovich became the bottom forward.
During that time LIND was scratched Games 2 & 4. He then became a regular starting game 5 until injured in Game 8 (10/20) and didn't return until Game 22 (11/28) and was a healthy scratch for games 26 & 27. He returned for game 28 and played pretty much every single game until the end of the season with the exception illness for games 55 & 56 and a 2nd injury for games 68 - 73. Healthy scratch 4 times, 2 of the first 4 and only 2 more times after game 4.
Carcone sat Games 1-3 and Game 7 after which he was a regular. Healthy scratch 4 times
Gadjovich was scratched Games 1 & 2, 4, 6, 8, 10, 18, 22 - 25, 27 & 28, then he got hurt and missed Games 33-35, back to healthy scratch for game 37 - 39, 46 & 47, 49 & 50, Injured in Game 53 so missed 54- 56, injured again and missed 64-70. Healthy scratch 20 times.
Jasek was scratched Games 1-3, 7, 24 & 25, 38 & 39, ill Game 42-45, 51. Healthy scratch 10 times.
You will note that Jasek, Gadjovich, and even Lind were scratched in that same stretch of games.
Petrus didn't want to have to put in the work that was needed to make him a dependable forward (if it was even possible) and couldn't accept that until he did, he was going to be scratched more than he was going to play.
