Flames GM Brad Treliving has been very active this summer in terms of adding pieces to help the team progress next season rather than regress.While he has made quite a few moves - notably trading for Dougie Hamilton and signing Michael Frolik - there is still plenty of work to be done.The team has several restricted free agents that need to be signed with the most notable being Lance Bouma, who was one of three Flames to file for salary arbitration on Sunday There will be a hearing scheduled for a few weeks from now but Bouma can still negotiate a new contract and sign on the dotted line prior to arbitration, which is what happens in most cases.Bouma is coming off a 16-goal, 34-point campaign and is surely looking to be compensated nicely.In saying that there are a few reasons I think Treliving should be wary of giving Bouma much in terms of a) length of contract and; b) dollars.Let's review.It's no secret that the Calgary Flames haven't exactly been possession darlings over the last couple years and Bouma is one of the reasons why.Regardless of who he has played with he has been on the ice for more shots/shot attempts against than for at even-strength and has served as an anchor to his linemates.Over Bouma's two-year NHL career all 11 players he has spent at least 250 minutes with at full-strength have fared better - in some cases significantly - without Bouma than with. That's not a coincidence.Nobody will question Bouma's work ethic or willingness to block shots, for example, to help the team.The problem is the reason he piles up so many is because he spends too much time - relative to his teammates - chasing play in his own zone. That's the case at full strength and that's the case while killing penalties, too.The objective while killing penalties is to avoid allowing a goal. Goals are scored by generating shot attempts. No regular on the Flames PK has allowed more shot attempts per 60 minutes played than Bouma.The difference in having Bouma on the ice as opposed to Backlund, for example, is more than 20 shot attempts per 60 minutes. That's a pretty significant gap.Bouma scored five goals in 78 games as a rookie. Bouma scored 16 goals in 78 games as a sophomore.Could it be he simply figured it out and can contribute offensively at this level? The numbers suggest we should be skeptical.Why?Well for starters his high in goals during four years in the WHL was 14. Very rarely do players produce in the NHL after struggling to do so in junior so there's a red flag right off the hop.Another red flag is that he shot 15.4% last year after scoring on just 6.1% of his shots as a rookie. It's possible he'll score at a better rate than he did in his first year, however, I don't think he woke up one day a much better shooter and is now 2.5 times more efficient than he was as a rookie.That shooting percentage is going to regress next season. The question is how much?Bouma struggles mightily in possession, is the team's worst penalty killer in terms of suppressing shots and he's unlikely to produce much offensively in the coming years.That doesn't sound like a player I'd want on my team for the long haul.If and when Bouma re-ups in Calgary I think Treliving would be smart to keep the term as short as possible.
