Jake Gardiner scored the overtime winner for the Toronto Maple Leafs on Saturday night.

The team that drafted him is in town.

I think we know which trade tree we’re doing today.

These trade trees are often long and sprawling but this one, with the exception of a little tidbit, is very simple.

The initial deal was made between Anaheim Ducks general manager Bob Murray and then-Maple Leafs GM Brian Burke on Feb. 9, 2011.

The Ducks got a veteran defender and long-time Duck in Francois Beauchemin, back with just one more season left on his deal carrying a $3.8-million cap hit ($3.65 million actual salary). Anaheim was heading to the playoffs again that season and Beauchemin had won a Stanley Cup with them just four years prior. Why not?

After Joffrey Lupul missed about a year due to back surgery and career-threatening blood poisoning, the Ducks were open to dealing the forward and his remaining two years at $4.25 million per season. Meanwhile, Lupul was looking for a fresh start. The Leafs were a great fit.

So, where does Gardiner come in?

Toronto initially requested another young defender from Anaheim, but the Ducks wanted the Leafs to take Gardiner instead. The club eventually agreed to take him as compensation.

(Oh, by the way, the other defender the Leafs wanted was Justin Schultz, who ended up bolting from the Ducks for nothing. Hindsight, right?)

Speaking of hindsight, the Leafs received a conditional fourth-round pick in this deal — and the condition is confusing.

I searched the internet high and low, and for the life of me I couldn’t find a definitive answer.

What I did find was that the Leafs would receive a fourth-round pick if Lupul was on the Toronto’s roster for 40 or more games in the 2012-13 season and a sixth-rounder if he was not.

We know that Lupul had a fantastic 2011-12 campaign with the Leafs, earning himself an All-Star appearance, but he only played 16 games during the 2012-13 season. Part of that was due to injury, but more importantly, that was the 48-game lockout-shortened season.

Ultimately, the Leafs received Anaheim’s fourth-round pick.

I have to admit that I couldn’t find the exact reason as to why this was the case, but the Leafs were indeed awarded a 2013 fourth-rounder by the Ducks. They ended up trading that pick to the Chicago Blackhawks as part of the package of picks that brought Dave Bolland to Toronto.

That pick went from Anaheim to Toronto to Chicago, and was finally sent to the San Jose Sharks, who used it to select Swedish goalie Fredrik Bergvik.

One thing I noticed about this deal is that every player involved got their money. After Beauchemin’s contract was up, the Ducks re-signed him to a deal that paid him $10.5 million over three seasons ($3.5 million per season).

After Gardiner’s entry-level deal ended, the Leafs signed him to a contract paying him $20.25 million over five seasons ($4.05 million per season).

Even Lupul, who was supposed to be a reclamation project, was rewarded for his success with the Leafs with a five-year $26.25-million deal ($5.25 million per season).

That’s $57 million and 13 years committed to three guys involved in a trade that didn’t even seem like a big deal at the time.

So, who won? That’s what trade talk is all about, right?

A few years ago, this was an easy slam-dunk for the Leafs. They got a a young up-and-coming defender in Gardiner and a potent — though often-injured — scoring threat in Lupul.

Time has made that a bit fuzzy. Lupul now occupies a spot on “Robidas Island,” sitting on Toronto’s injured reserve.

I highly recommend listening to Elliotte Friedman’s radio hit on the matter:

I also recall Chris Johnston pointing out on my podcast that Lupul’s spot in the Leafs’ locker room had been given away during last season while Robidas’ still held his own equipment.

Should Lupul’s current circumstances alter how people look at this trade? I would argue no. Lupul performed well when healthy and it was then-Leafs GM Dave Nonis’ prerogative to sign him to a five-year deal despite the known injury risks. Plus, nobody plans on being injured.

The term “injury-prone” gets thrown around a lot with Lupul. It seems his back issues have come back to haunt him, but I always like to point to this video clip:

Lupul suffered a broken arm because a teammate hit him with a slap shot while he battled for position in front of the opposing goal. Like, come on.

I don’t want this to turn into a post all about Lupul. That time will come.

The Ducks’ end of this trade tree is over. Beauchemin signed with the Colorado Avalanche as an unrestricted free agent in July 2015, so that’s that.

The Leafs’ end is continuing in two very different ways. There’s the Lupul end, which is still very confusing. Then there’s the fact that Gardiner may actually be the Leafs’ best defender on many nights.

Luckily for Anaheim, nobody is looking at them and going, “If only they had Jake Gardiner!”

The Ducks have assembled one of the finest young defences in the NHL. That being said, this deal is a great example of there being no such thing as a “nothing” trade.
