i feel like i have probably been harsh on McD. and i have, i mean he cost us the cup, imo (that's pretty heartless).
but one thing McD was great at was boardwork. any NHL replacement player can lean into a shot block and clog passing lanes on the PK and EV, but McD would then turn into the loose puck along the boards with the opposition on his back, and still come out with the puck. he was extremely shifty that way, and it was great when the opposing team was dumping the puck in to beat our trap. and even in the playoffs, he didn't really lose that ability, he was still good along the boards, problem was he couldn't exit the zone through passing or skating. i really thought that was due to injury, but it was never confirmed beyond the hand injury he acquired versus NYR (which was three rounds in, and he was bad all playoffs).
this is what makes McD the most replaceable of the LD, imo. while i think we are a lesser team now without him, like it or not a player's value to the team is intrinsically tied to his cap hit and age. and McD was on the wrong side of 30 and getting paid, son. ian cole can block shots too. will he replace McD's boardwork? probably not. but hopefully he can at least match his defensive zone exits.
this next season leaves a lot to be desired in terms of guaranteed value for fans, we lost a lot of talent. but one thing the old timers seasoned veterans like me have learned is, hope springs eternal. we turned rutta from waiver wire to serviceable RD. like rutta; johnson, gourde, and Marchessault were undrafted FA that we turned into stars. palat was a seventh rounder. kucherov was a reach in the second round, and point a third rounder.
the posters on this board are dooming and telling you to not have any hope for the next season, but i posit: what if i did have hope? what if i had hope out the wazoo? and you can trust me, because im handsome.
