I will only speak for me.
I defended Clarkson's play last season because I feel he was always a step behind. But there got to a certain point where that stopped being a reason. Lupul always misses huge chunks of games, and he never looked that loss.
This season he was given every single opportunity to succeed and he was "good" for the first month and then just fizzed out. His play was putrid. He was on the powerplay and had 1 point ALL. SEASON. (someone had the numbers, but Clarkson was near the bottom of the list (like 300+ above him had more).
Compared to the entire load of poop this team has dealt with - the only thing that Clarkson really got (overall) from the media was that "oh, he's just not good enough." Yes, Mirtle was harsh on him, and Ferraro was hard on him, but on the whole? Kessel has gotten a tonne crap more than Clarkson. Phaneuf, Bozak, Lupul, etc have gotten a lot more criticism.
For all the things i hate about Phil and Dion at least these two go "well at least we're not good." out of 118 games how many "good" games has Clarkson had, and he gets benched twice, and "well it's not because of ME it's just a message to the team." No dear, it's a message to you too. you. stink.
I truly hope he (Clarkson) can be "good" in Columbus, whatever "good" means for him. but let's not make it that Clarkson never had opportunities to do well. He was never going to live up to the contract (fair), he was never going to score 30 again (not his fault), but let's not make it like all he did was play 3 minutes on the 4th line either.
