You're going off by our recent practice lines I assume? Him being on the fourth pair was only due to handedness (hes playing left handed RD with Zadorov a lot, but Boqvist is back and Bowey needed a LD partner).
Almost all of us are sure it means nothing, coz JC is playing 7D basically all the season as is - although he's shown to like the occasional scratch for young guys too. The handling of the young guys definitely follows the same pattern. Dach and Mitchell were the same, give them limited time until they earn it consistently, and then basically no looking back. I like it actually, he's really easing them in, but makes sure to reward them.
Beaudin is trending super well. JC is a huge fan, to a point where it's a running joke for us. He can't stop gushing about him lol. I expect steady bigger minutes after the trade deadline. Well deserved too, his strength and thus game imrpoved significantly this off-season. Very steady and calm.
