A self rental would be a terrible idea if the end result is another Carolina-style bounce out if the young talent isn't ready. Despite all the talk about "competing teams don't sell," you have to take a good hard look at whether this team is actually a contender for something more than a quick exit or even winning merely a round. NHL GMs do a lot of dumb things that they shouldn't, so just because the team may or may not do something doesn't make it wise.
Go ahead and chalk me up in the "100% against," category. If they've decided they cannot afford a 5 year, $5m+ contract for Buch, and they honestly probably cannot since ultimately that's probably a salary they are paying to a third liner or at best their 6th or 7th most important winger, then he should be dealt if the return is even a Hayes-like one. But given last year's deadline, probably more.
