Let's ask Michael Grabner, who was placed on waivers after a less than stellar Camp.
Coming from Vancouver in the Keith Ballard deal, he had a decent season on the left coast (20 gp 5-6-11) after posting pedestrian numbers in Manitoba of the AHL. Even so, coming into Florida, you think he would have a pretty good shot at cracking a Panthers roster that included the likes of Stepen Weiss and David Booth.
I know VERY little about the situation as to why he was cut. PKLC Insider Caity Kauffman has her take on it;
"He didn't exactly produce in the preseason, I believe he was a minus 4 or 5 and didn't contribute any points at all for Florida However, considering we acquired him in a trade for Ballard, I'll take Grabner over Ballard any day"
Coach Peter DeBoer also said he 'lacked finish'. Again, these are the freaking Panthers.
He's still young, so there might still be hope for Grabner, but this does put a dent in his NHL career.
