I feel comfortable with that state of affairs for any team. A lot of people seem to think that the goal should be to spend to the cap ceiling every year. To me, the more sensible thing is that teams should generally be spending around halfway between the cap and floor, and then ramping up to the ceiling when they are in contending years. That way, the team is able to capitalize on revenues to make a profit, which enables them to spend more on promoting themselves, which brings in more money, etc. After all, the owner should be able to reap some financial rewards rather than just blowing money all over the UFA market.
Personally, I start to get worried when a team is losing money in spite of scraping the cap floor. At that point you know that something is seriously wrong with revenues. But until then, it's just a matter of running a tight ship and making good decisions.
This may or may not have to do with Nashville's finances. Even if Poile was willing to throw money at Suter and Rinne, that doesn't guarantee they will sign a deal. It's understandable that Weber wants to wait and see what happens with those guys, regardless whether or not the Preds are willing to pay for them.
