Just as quickly as it arrived, it's gone.

The NHL's trade deadline came and went Monday afternoon with a flurry of deals—including one involving last fall's highest-profile free agent—that reshaped the rosters of the league's top contenders while restocking the cupboards of some teams most in need of a talent upgrade.

But while Taylor Hall to Boston and Anthony Mantha to Washington provided plenty of buzz, there's just as much chatter in the aftermath about players and organizations that didn't produce a blip.

That's surely a downer for some fans. But it's just fine for the B/R hockey squad.

Our cadre of puck heads took a look at things through an analytical lens and came up with a handful of deals that should have—or at very least could have—been made before Monday's window slammed shut at 3 p.m.

Click through to see what we came up with and take a moment to drop a thought or two of your own in the comments section. And hey, if your team is among the ones mentioned, consider it free therapy session.

Rickard Rakell to Edmonton from Anaheim

Of the offensive players perceived as available at the deadline, few surpassed Richard Rakell.

The Swedish-born winger has been a go-to scorer for most of his NHL career, peaking at 34 goals in 2017-18 and adding double-digit seasons of 33, 20, 18 and 15 for a per-year average of 23.

That's attractive enough, without mentioning he's got another season on a deal paying $3.8 million per.

Meanwhile, you have the Edmonton Oilers.

Their top-line players have both Hart and Art Ross trophies on their mantel, but the need for proven and consistent scoring to fill out the top six was no secret heading into the weekend.

And while the salary cap situation was surely challenging, several other teams with equally difficult financials—Tampa Bay, for example—still managed to bring in a worthwhile asset by Monday.

Rakell seemed a good fit for a team in need of help against the likes of Winnipeg and Toronto in potential playoff matchups. You have two of the league's best players in the primes of their careers, why not take a chance?

Sam Reinhart to Pittsburgh from Buffalo

Sam Reinhart was the second overall pick in the 2014 draft, between two guys named Aaron Ekblad and Leon Draisaitl, and has been a consistent performer in the NHL since his arrival,scoring 20-plus goals in four of five full seasons with a low bar of 17 in the other.

So, given that he's making $5.2 million this season heading into restricted free agency, getting the 6'2", 193-pound winger at age 25 was going to require a long-term investment.
