Both the limbs Erik Karlsson tested Thursday seemed strong enough.

The one the Senators' top defenceman seriously injured last February and the one he ventured out on for a prediction after seeing Jason Spezza work between Bobby Ryan and Milan Michalek for the first time during Day 1 of on-ice action at training camp.

"If they can play together" Karlsson said of the team's promising new forward combination "we're probably going to have one of the best lines in the league."

Two out of three ain't bad either Meatloaf and Senators fans might add.

Should they stay healthy the potential is there for Spezza and Ryan to finish 1-2 in the NHL scoring race. Yes that's being optimistic (nobody has screwed up yet to warrant criticism) but it's also a theoretically sound claim.

Spezza is one of the NHL's best playmakers and Ryan is among its top snipers. Could he score 50 feasting on dishes served up by Ottawa's No. 19? Why not? Dany Heatley did. Twice.

"Bobby's a little bit different player" said Spezza. "I think he's probably a little bit better with the puck moving it a little better. Heater shoots it a little better probably off the one-timer. But I've only skated with (Ryan) for a week and half -- (and) it was just scrimmage with a few guys."

So maybe Ryan's shot is near as good?

"I don't see why he doesn't have a chance to score a lot of goals" said Spezza. "But a lot of things have to go right to score (50) in this league and less and less guys are doing it."

Why? Spezza says it's because since Heatley's hey-day (just after the second-last lockout) power-play chances are down systems are tighter and players are skating better.

But John Tavares had 28 in 48 last season and who did he have feeding him?

"We're a little ahead of ourselves there" Ryan said laughing when asked if he felt like making the bold promise of a 50-goal season on the second day of camp. "I'll predict getting one early then feeling much better about it. It would be nice. That's about all I can think about right now."

Ryan admits he generally sets for himself a goal of scoring 35.

"If you scored 40 and you're a minus-1 what did you do really?" he said. "So if I can score 35 and be a plus-20 I'll take that all day.

"That's the goal for me this year. I've set personal goals ... it's to continue to be a plus-player."

He also said he liked a quote he read in the papers earlier this week from Spezza about not "forcing" passes between them.
