I think you have enough established stars on your keeper roster to go for "higher upside" player here. I think that Johanssen will have a few more years with 70+ points than Staal. Go with RJ here.

I'm a proven over potential guy. If you are in the running to win in the next couple of years, definitely Staal for me.

Your keepers are win now keepers. Staal will add nicely to that. I love RJ and I like his age and upside quite a bit. I'd like to see more of a consistent sample size of his production beyond one year. I side with Staal's history here.
How big is your league?

Just wanted to point out the snide comment here at the end.
I like to spot trends and have somewhat decent success rate(won't toot my horn too loud though) you look at some of the key stats over the last three full NHL seasons(hard to count a lockout shortened season IMO) and you'll notice a trend...look at goals, points, power play goals, power play assists, shots on goal and point per game ratio...all trending down three years in a row. He'll be 30 in October. Noticeable drop off in play and effectiveness with ye old faithful eye test. Carolina is a team in transition and major changes are expected this summer. It's fast becoming Jeff Skinner's team. So add in the fact Staal could be traded to Toronto or Vancouver or Edmonton or where ever...and who knows how he responds to that...there are plenty of reasons to suggest Eric Staal is not the best option for the OP and he should go with Ryan Johansen who has been phenomenal this season. Eric Staal has been inconsistent the numbers show that and the drop off in play shows that.
Furthermore...Johansen's talent has never be a question. Many of us have been expecting this kind of season from Johansen but it took him a little time. He had some issues with consistency himself to iron out, as well as attitude and effort. He was benched in the AHL playoffs this past season...that was his wake up call and he worked his tail off to improve in the areas Jarmo Keklainen and company told him to. Results are there before us. There's no regression coming here...Johansen is the CBJ's #1 center moving forward.
i am not sure Johansen is going to be a consistent 70+ player, people for some reason ignore the reality of what goes on in the NHL
the number of 70+ players has been going down and it was less than 20 this past season
Johansen is a very good player but i find it difficult to believe he will be a top 20 forward in the league for multiple seasons
not every player is going to have multiple 70+ point seasons just like not every player has 100 point upside
