Saying he can be is the same as saying he won't be. Both are possible. IMO it's time to trade him not only because of his uncertain skill level moving forward but because of a multitude of reasons.

He seems to have lost his drive in most games. Not all games, but he doesn't look the same.
His contract status moving forward.
Other teams needing to make additions (Buff, NJ and a slew of other teams)
The increased odds of signing Hall, another good LW, as a free agent.
The team's need for change. Unless they win the cup this year, or at least go deep a couple rounds, the team needs a major change.
Positional need. If a team is going to give up a high end C prospect like Cozens, the team needs to jump at the chance to strengthen that position.

There are a lot of reasons to trade Johnny if things don't improve these playoffs, even if they do because it might boost his value. Their window is closing with the current core IMO, the team is not a contender and they need to improve. If they can improve by trading Johnny or anyone else, they should. Some people may say that trading Johnny doesn't improve the team because he's good. They're right...if there is 0 return or asset gain. Trading Johnny for 2 or 3 strong pieces helps and then if they can sign Hall, who isn't as good, they still come out on top. I've said it before but it's like trading a $20 bill for 3 $5 and a $10.
