Let's look at how Gillis did with his picks compared to what was actually there to be had. I'm only doing the first 4 rounds as, generously in the case of the 4th round, this is where one would expect to find players. Anything from the 5th round onward is gravy.
2008: Gillis was hired in April and wouldn't have done much if any of his own research going into the draft this season.
Pick 1: Cody Hodgson - We know this story, but it's difficult to fault Gillis for this particular pick. At the time there was no way of knowing that Hodgson had an undiagnosed medical condition hampering his play. TSN had Hodgson ranked 9th and we picked him 10th so it's hard to argue that we didn't take the perceived BPA at the time.
Pick 2: Yanne Sauve - This one sucks. There were three hits in the next ten picks and it would have been a great benefit to us to have picked Wiericoch or Stepan, Shultz would have been a good pick but we know that he didn't sign with the team who drafted him and rejected our offer when he became a free agent.
Picks 3 & 4: We didn't have any picks in the 3rd and 4th round in 2008.
2009: Gillis's first draft with a season under his belt as the Canuck's GM.
Pick 1: Jordan Schroeder - This was a pretty large swing and a pretty large miss. That said he was 15th on TSN's list that season. Some people will say that we should also have passed on him after he fell 7 spots to our pick but hindsight is 20/20. The biggest pain here is that within 10 spots of him two nice hits in Johansson and Palmieri then just one pick outside of that range a huge hit in ROR.
Pick 2: Anton Rodin - We went off the board entirely to take a stab at Rodin (who's signed another NHL deal with the Ducks this offseason) had we stayed on the board it's possible we end up with Gelinas, Tatar, or Pirri (Orlov is out as we were very against drafting from the KHL at this time) any of those picks is vastly better than what we got.
Pick 3: Kevin Connauton - This pick was actually a hit, just not for us. Compared to most of his peers K-Conn has done pretty well not a home run but a solid hit for our scouts.
Pick 4: Jeremy Price - Hard to complain too much as only two players drafted within the next 10 picks went on to play more than 100 NHL games. I guess Chiarot would have been a decent get, but when the next best player is Froese it's hard to say we really missed out on much.
2010: Gillis's second full year as GM.
Picks 1, 2 & 3: We had no picks in the first three rounds of this year's draft. Given where our team was at it's hard to fault Gillis for spending picks on NHL ready assets.
Pick 4: Patrick McNally - A pretty big bust, but at least we traded him for a pick later. Again there wasn't much quality within the next 10 picks but a Hyman or Wagner would still have been nice.
2011: The draft after a heartbreaking run.
Pick 1: Nicklas Jensen - Obviously a bust but he was ranked 24th and we picked him at 29th. Another faller that didn't pan out. We could have had Rakell, Jurco, Jenner, or Gibson that means 4 out of 10 teams just flat out beat us. Those other six teams ended up with pretty much the same level of player, so it feels a bit like we lost a coin flip.
Pick 2: Traded.
Pick 3: David Honzik - Another whiff, but at least this one was a goalie picked around where you'd like to see goalies picked. No goalie picked after Honzik amounted to anything and no player taken within 10 picks of him played over 200 games or reached 35 career points.
Pick 4: Alexandre Grenier - This wasn't that bad a pick even if his NHL upside was never there. He gave our AHL teams solid service and of those players picked after him only JG Pageau was something worth worrying over.
Pick 5: Joe Labate - Another AHL lifer who's a solid soldier at that level. It hurts that we missed Gaudreau but the other 9 players we let past us were exactly the same level as Labate.
Pick 6: Ludwig Blomstrand - A total whiff but there was nothing in the next 10. Closest thing to an asset was Claesson but 20 points in 113 games isn't anything I'm losing sleep over.
2012: Another year another draft.
Pick 1: Brendan Gaunce - We can rag on how little Gaunce does offensively but in the next ten spots he's competing with Skjei and Pearson. Pearson is the only player I'd lose sleep on but getting Gaunce still means we did better than 8 of the next 10 teams managed to do.
Pick 2: Alexandre Mallet - Not sure what the plan was here... Severson and too a far lesser extent Martinook would have been the home runs here, but really we did the worst we could have done with this pick.
Picks 3 and 4: Traded.
2013: Gillis's final draft.
Pick 1: Bo Horvat - We won this one. It's hard to argue that we didn't get the best player out of every player within 10 picks of Horvat. The only player who's close is Wennberg so I guess watch this space because Horvat could wind up being the second best player taken in the top 19.
Pick 2: Hunter Shinkaruk - He busted, but so has pretty well everybody taken in the next 10 picks. That said, there are players who are at least still playing in the NHL taken near him. Hard to fault trying for the small skilled player but this was a swing and a miss.
Pick 3: Cole Cassels - We know this story. Looked great in juniors but has struggled to be more than a 3rd liner at the AHL level and even that is being generous. The good news is there are only two players who would have been NHL players for us in Andrighetto and Bjorkstrand now that Slepyshev has gone back to the KHL.
Pick 4: Jordan Subban - Another small skilled pick who just couldn't overcome his lack of size. The only hit we could have landed is Butcher and that's the home run pick for the entire 4th round. We have the other player worth having from the next 10 spots having acquired Motte.
Those are all the picks in the first 4 rounds under Gillis. It honestly feels like he just got unlucky when you look at the players taken within the next 10 picks of what we actually took. It hurts looking at what we could have had in some cases, but in every case, there are at least 6 other teams feeling the same way. In many of the later rounds even if we got the biggest hit all we would have had was a few seasons of a replacement level NHLer.
It's easy to throw stones with 20/20 hindsight and we did do worse than average over that span but it really feels more like bad luck than bad methodology with most of our picks.
