Girard is a top pairing dman on half the teams in the NHL. He eats 20+ minutes a game, scores 30+ pts with no PP1 time, has great shot share metrics, and is a good defender in that he uses his skating and stick work. He gets crapped on because he isn’t 6+ ft tall.
If you're using TOI as a blanket metric as where a defenceman should play up and down the lineup (which I for the most part agree with) then
exclusively among LHD, Girard is 37th in the metric. It's not hard then to follow the logic that if there are 32 teams in the league thus 32 top-pairing LHD, Girard is more appropriately in that transitory zone of "good top-4, poor man's top-2". Expanding that search to disregard handedness should produce 64 top-pairing defencemen and Girard once again falls a hair short at 70th.
His counting numbers definitely fit that bill however. Girard is one of the more reliably productive defenders in the league.
He's an excellent top-four name, one that I quite like to be honest, but I think it's yet a stretch to label him a bonafide top-pairing defenceman. If you subscribe at all to age curves, he still has a couple years to reach that echelon but otherwise is going to make a career out of being one of the better second-pairing defenders in the league. Perhaps he doesn't adjust fully to a proper top-pairing role? Perhaps he does.
To fully conform to your statement, I think Girard would be a top-pairing defenceman on
maybe 10 teams in the league. 12 if we ignore handedness.
