Our right side D is perfectly fine. I'm not sure if you're aware of this but Pietrangelo is also a right side D. How do you expect having another right side D to fix our left side, the side that's the actual problem? Also I would like to ask, if someone is constantly playing above their weight class, when does that actually become their weight class?
I'm not sure if you're aware of this, but in leagues with salary caps, free agency, and trading the decisions made at one position very often wind up impacting other positions.
The Faulk acquisition and extension was one of two things. It was either insurance in case we couldn't reach a Petro agreement or it was a proactive long-term replacement for Petro because Army already knew that there wasn't a deal to be reached. I tend to think it was insurance. But either way, it was an acquisition clearly motivated by not being comfortable with extending Petro at market value.
Let's imagine we extended Petro for the contract he got from Vegas (or potentially a slightly lesser AAV with the extra year tacked on). This helps the LD today a few ways.
First, Petro is a better #1D than anyone on our roster and can do more with a lesser partner than either of Parayko or Faulk. The caliber of LHD man we need to put with him to make an effective top pair is less than the guy we need to put next to Parayko or Faulk.
Second, it would have meant one of two things. Option 1: we never acquire/extend Faulk. Bokk can be used for something else (maybe a LD at some point) and today we have Petro/Parayko still with a lot of term. Option 2: We do acquire/extend Faulk and as of 2020 have Petro/Faulk locked up long term. We then have the ability to trade Parayko with either 1 or 2 years left of term for an absolute haul (some of which could address the left side). Or we let him walk after trying to go for a couple runs and still have Petro/Faulk on the right side today. Either way, the right side is in better shape than our current right side that you described as simly 'perfectly fine.'
Third, we're not signing Krug in a world where we extended Petro. Whether Faulk was here at that point or not, we simply wouldn't have had the cap space. Which means Dunn gets a chance to step into the offensive D role that year instead of all the sheltered minutes going to Krug.
In a perfect world, we'd have extended Petro, never acquired Faulk, never signed Krug, and protected Petro/Parayko/Dunn at the expansion draft. Those three cost $19.3M against the cap this season, which is $200k less than we spent on Parayko/Faulk/Krug. In a less perfect world, we'd have had Petro/Faulk/Dunn (still $200k more) and a boatload of assets from trading Parayko in 2020 in preparation of the expansion draft.
The D as a whole pretty clearly would be in better shape with that trio than the Parayko/Faulk/Krug trio we actually have.
Oh and do you know HOW I know our team would still suck right now even if we had Pietrangelo? Because our Defense sucked in 2018/19 for the first half of the season even with Pietrangelo and Jbo Because the coaching sunk the team, just like the coaching is sinking us now and no amount of good Dmen will fix a tank job caused by the coaching.
When Yeo was fired, every one of our defensive metrics (expected goals against, scoring chances against, high danger chances against, shots against) was average or better. It was the scoring and team save percentage that was near the bottom of the league. The coaching change made a large improvement to the D, but the defense absolutely didn't suck before then. The were average (or maybe slightly above average) and then the structural change led to them being top 5.
I agree with you that we had a big structural issue defensively this year that made our group play worse than the sum of its parts. But the play of the D this year was
significantly worse than the play of any Blues team from the time we hired Hitch to the time Petro left. There is no extended stretch from that era comparable to what we watched this year.
