No, he would not. Good player, elite spin-o-ramas - but posts like this are completely over the top. Girard is not a top 30 dman and any team he is a #1 on is a sad team indeed.
Ok, why isn't he a Top 30 Dman?
He ranks Top 30 in basically every stat you can find since he really had his breakout season in 2019/20. So why isn't he a Top 30 Dman?
He ranks 14th in CF%, 17th in FF%, 15th in SF%, 13th in xGF%, 8th in SCF%, 28th in HDCF%. He's also 29th in points among Dmen scored since 2019/20, 27th for Even Strength points, 29th for Even Strength Points/60. And he's 16th for TOI/Game at even strength.
He's not sheltered, he plays the most minutes at 5 on 5 of any Avs defender. He's got Top 30 stats in basically every category. And if you dove further into the analytics you'd see articles across the league ranking Dmen for Win Shares or Wins above replacement level and see that Girard ranks well inside the Top 30 and quite frankly inside the Top 20, in every single one of those articles. Not to mention he's the best transitional Dman in the league.
By the stats, not only is he a Top 30 Dman, he's actually more like Top 20. But I get that his size hurts him a little compared to most of his peers around him. But saying he isn't Top 30 is just ridiculous. He absolutely is.
