As a side note, I believe they tried Sanford at center last year for a stretch. I wonder if they are hoping he can be a bottom 6 option at center, or if it was out of necessity with so many regular centers injured.
It was definitely out of necessity. We had a month long stretch where Thomas, Bozak and Barby were all injured. DLR got hurt about 10 days into that month and we spent the next three weeks or so missing 4 of the club's top 7 centers. It was during that stretch where we tried Sanford at center, but it was short lived because he just isn't a center. Dakota Joshua took over 4C duties with ROR/Schenn/Sunny centering the top 9. Bozak returned, Sunny immediately got hurt, and then Thomas returned to get us back to reasonable center depth.
Even with us spending a month with only 3 NHL-caliber centers on the roster, Sanford still only took 68 faceoffs last year. It was definitely a move out of necessity and not a move done with the hopes that he could be a long term center. Additionally, I don't think that bottom 6 C is an area of weakness for us that would encourage us to try new guys there. Despite the trouble we got into last year, our center depth is pretty damn good. ROR, Schenn, Thomas, Sunny, and Barby were all brought up as centers and I'm comfortable with 4 of those guys playing 3C. Barby is best suited as a winger IMO, but is capable of playing adequate 4C.
I think we have a top 5 center group if Bozak re-ups here. If not top 5 then right at 6th. ROR is a consensus above-average 1C and is arguably just inside the top 10 centers league-wide. I have concerns about Schenn's contract, but he finished 38th in points and 37th in goals among centers last year. He was 24th in points and 20th in goals the year before. 46th and 65th the year before (although he missed 10 games). Taken together over the last 3 years, he is 35th in points, 31st in goals and 36th in points per game (minimum 100 games played). He is a top-tier 2C since ROR got here and was a decent 1C the year he was used in that role here.
Now, there are few teams who have a 1-2 center punch that is substantially better (McDavid/Drai, Sid/Malkin, Matthews/Tavares, Point/Stamkos) and 1 team with a superstar 1C who erases the gap between Schenn and their 2C (MacKinnon and Kadri). After those 5 teams, there are a number of teams that have an arguably comparable/better 1-2 punch at center (Aho/Trochek, Giroux/Couts, Scheifle/Copp, Zibanejad/Strome, Backstrom/Kuzy, and let's throw the Isles and Stars in there for good measure).
For 1 season, I would take ROR/Schenn over every tandem in that second group (although Carolina and NYR make me stop to think). Even if you like a few of those other tandems better, our depth out shines the bottom 6 centers for those groups. Thomas, Sunny, Bozak and Barby as centers for the bottom 6 is better than any of the bottom 6 center groups for those teams and Bozak/Thomas/Sunny are all capable of sliding into the 2C role for a few weeks to tread water with an injury to Schenn/ROR. That depth makes us the clear best center group among that 3rd tier and I'd argue that it leap frogs us over 1 or 2 of the elite 1-2 punch teams. The center depth in Toronto is bottom 10 in the league and the jury is out on how Tampa's center depth looks with Gourde and Johnson both leaving this summer. I like Cirelli, but they are fully unproven after that.
From top to bottom, I think we have the 5th best center group in the NHL if we can get both Bozak and Thomas onto the roster. If not 5th, I don't see how you could slide us lower than 6th or 7th. Without Bozak, it probably dips a few spots, but is still top 10.
Edit: And Bozak is back! Sign Thomas to anything under $2.4M, run a 22 man roster and you have a cap compliant team with a top 5 center group in the league. God damn right Army.
