Of the 20 players in uniform for the Bruins’ 2014-15 season opener last Oct. 8, just six were drafted by the team. And only two — Ryan Spooner and Craig Cunningham — were taken after 2006.

This is a problem. Poor drafting not only explains why the B’s could not weather the storm of injuries well enough to get into the playoffs last season, but also why they find themselves in the financial crisis they’re in today. They just don’t have enough good, young, cheap players in their system.

No team hits a home run with every pick. Every team endures missteps, even the best ones. Drafting teenagers — undeveloped physically, mentally and emotionally — is risky business.

HARRIS: Don Sweeney has deep NHL draft to change Bruins' luck

Still, some teams manage to do it better than others. The Blackhawks have remained an elite team through salary cap purges by drafting well. The same was true for the Red Wings before them.

While the Bruins had been an elite team on the ice for a good five, six years in the Peter Chiarelli era, it wasn’t accomplished by drafting well.

The B’s have had better results the last few years. Dougie Hamilton, their first-round pick and the No. 9 overall selection in 2011, might round into a No. 1 defenseman. David Pastrnak, last June’s first-round pick and 25th overall, defied the odds and contributed to the big club almost immediately.

Chiarelli’s fingerprints were all over the 2011 Stanley Cup team through trades that brought Nathan Horton, Johnny Boychuk, Adam McQuaid, Andrew Ference, Chris Kelly and Rich Peverley to the Hub.

But if Chiarelli had better drafts, he might still be the GM.

Here’s a year-by-year look at the drafts, from 2007 to 2012:

2007: A whiff of failure

Chiarelli was still at the Ottawa table for the productive 2006 draft that netted Phil Kessel, Milan Lucic and Brad Marchand, so his first draft was really this one. And it was probably the biggest whiff of all. With the eighth overall pick the Bruins chose bust Zach Hamill, while Logan Couture went to San Jose with the next pick. Also left on the board was Ryan McDonagh (Montreal, 12th), Kevin Shattenkirk (Colorado, 14th) and Max Pacioretty (Montreal, 22).

The second round wasn’t much better. The B’s traded up to get Tommy Cross at 35 while Montreal nabbed P.K. Subban at 43. Cross might have been a very good NHLer if not for injuries and remains a good character player in Providence, but Subban is a dynamic star. The rest of the B’s crop that year — Denis Reul, Alain Goulet, Radim Ostrcil and Jordan Knackstedt — never made the NHL.

2008: Help . . . for other teams

In hindsight, this draft turned out a little better than it was originally thought to be, though the B’s themselves didn’t profit. Joe Colborne was taken with the 16th pick and, after being dished to Toronto in the Tomas Kaberle trade, appears to have gained some footing in Calgary. Goalie Michael Hutchinson, whom the B’s gave up on, was taken in the third round (77th overall). He found a home in Winnipeg and battled Ondrej Pavelec for the starting job. Had the organization stuck with him, he’d have made a good backup for Tuukka Rask, which they needed.

Their second-rounder, Max Sauve, was again a miss. Sauve was taken with the 47th pick while Derek Stepan (Rangers) and Travis Hamonic (Islanders) went 51 and 53, respectively. The rest of the picks — Jamie Arniel, Nick Tremblay and Mark Goggin — did not make the NHL.

2009: It starts with Caron

Bruins fans no longer have Jordan Caron to kick around anymore after he was traded to Colorado at the deadline last year, but for a long time he was emblematic of the team’s drafting futility. The B’s were picking low in ’09 at No. 25, but they still passed on Ryan O’Reilly (Colorado, 33) and Jakob Silfverberg (Ottawa, 39).

Third-rounder Ryan Button was a throw-in in the Tyler Seguin deal and fourth-rounder Lane MacDermid was in the Jaromir Jagr deal with Dallas before retiring. Sixth-rounder Tyler Randell and seventh-rounder Ben Sexton could be darkhorse fourth line candidates in September.

2010: Spoon-ful of potential

This draft appears to be better than most, and not just at the top. Thanks to the Phil Kessel trade, the B’s were blessed with with the Nos. 2 and 32 picks. The second pick, Tyler Seguin, would eventually be traded while the 32nd pick, Jared Knight, never came close to making the Bruins. Justin Faulk was picked by Carolina at 37 while Tyler Toffoli went to Los Angeles at 47.

But even with the trade of Seguin and miss on Knight, this draft could still pay big dividends. Ryan Spooner (45th pick) appeared to save his career just in time and is on track to be the third line center next season. After a stellar career at North Dakota, goalie Zane McIntyre (165th pick) is one of the team’s top prospects, and defenseman Zach Trotman (210) will most likely be in Boston next season. Craig Cunningham (the 97th pick later lost on waivers) and Justin Florek (135) also showed flashes they could play in the NHL in bottom six roles.

2011: A hit with Hamilton

Though debate rages on just how good Dougie Hamilton is right now, there’s no question he was a hit at the ninth spot. Skillful forward Alexander Khokhlachev (40th) will get another shot to make the B’s in camp, big winger Brian Ferlin (121) looked promising in his call-up, and the organization is happy with the development of Yale defenseman Robbie O’Gara (151). Anthony Camara still seems like a reach at the 81st pick while Boston College’s Johnny Gaudreau was taken 104th by Calgary.

2012: Too early to pull goalie

It’s not that Malcolm Subban didn’t deserve to be picked in the first round (24th) — he still looks like a good prospect — it’s just curious the B’s were the team to take a goalie so high. Even with the news of Tim Thomas’ odd semi-retirement about to become public, there was a succession plan in place with Tuukka Rask while Zane McIntyre had been drafted two years before. Tanner Pearson, taken 30th by Los Angeles, might have been a better pick, but we shall see.

If Subban pans out as a No. 1 and the B’s can one day afford to move Rask’s big contract, it might work out.

But that doesn’t help them out of the mess they’re in right now.
