This goes back to handing out all these bad contracts. The B's idea is acquire or retain big, less skilled players. See McQ, K. Miller, Beleksey and Hayes. This is what you get. Guys that simply don't produce.
The guys you listed combine to make $18 million. If you add K. Miller, that's $20 million. They probably would've been better off atleast for this year going and spending all that money on Stamkos and Yandle and filling in with minimum guys around them. It's just crazy to me all the missed opportunities and horrible cap/asset management. These are the results you get.
But you know what, we can bemoan the bad contracts, yada yada, but at the end of the day, this team isn't up against the cap right now. They haven't not acquired top players because of cap contraints, they haven't acquired top players because they haven't been capable of acquiring top players.
This team isn't being held back by some cap issues preventing upgrades. This team is being held back because:
A) The overall collection of players simply aren't good enough.
B) The higher end players they do have outside of Pastrnak, Chara, Carlo, and Rask, haven't produced anywhere close to expectations, even Saint Patrice and Marchand (subtract his 5 pt game and his numbers are average at best).
As it stands this team has to play perfect defensive hockey to have a chance to win. Secondary scoring from both the forwards and the D is almost non-existent (the addition of Kevan Miller certainly isn't going to help in that regard). Primary scoring is also an issue.
Meanwhile, we have a coach and staff who refuse to admit their 1st PP unit isn't working (well it worked last year I believe was Claude's comment), and a template for forward line combinations that has resulted in the Bruins being near the bottom of the pack in terms of goals scored at the 20 game mark with no apparent changes in sight.
