When describing Mercer as a "defensive presence" on a line, we need to keep in mind that -- I've been saying for quite some time -- this is a ridiculously skilled and smart kid whom I'm confident will score a whole lot of points in the NHL.
At tsn.ca, Craig Button just released his updated top 75 prospect rankings. I'm a huge supporter of Button, whom I feel has iconoclastic opinions which he consistently backs with reasonable explanation. That being said, his top 75 rankings were just... well, the only word I can think of right now is
abominable.
Detroit Red Wings' blue chippers, Montreal Canadiens' Cole Caufield headline Top 75 prospects list - TSN.ca
Button had Mercer as the Devils 4th best prospect, at #52 overall. For contrast, I have Mercer as the Devils #1 prospect, in my top 10-15 overall among NHL prospects. Other highlights include gross under-rankings like Byfield at #17 and Victor Soderstrom at #75 alongside gross over-rankings like Philip Broberg at #8, Ivan Chekhovich at #60, and Jakub Pelletier at #51, one spot ahead of Mercer. I mean, I'm a fan of Pelletier, but anyone who as seen him on the same Team Canada as Mercer or the same QMJHL as Mercer and can say Pelletier is any way superior to Mercer while attached to a polygraph test might have a future as an international spy.
For contrast, here's my top 10 prospect rankings, with the Button rankings in parenthesis:
1 C Byfield (LA) (17)
2 C Turcotte (LA) (22)
3 RW Caufield (MTL) (2)
4 LD Sanderson (OTT) (7)
5 RD Seider (DET) (1)
6 RW Jarvis (CAR) (26)
7 LW/RW Raymond (DET) (3)
8 C Rossi (MIN) (31)
9 LW Boldy (MIN) (5)
10 C Lundell (FLA) (6)
I'd say Mercer would be pretty close to this top 10 list, definitely in the running at #11 or #12 with Kaliyev. My next D would probably be Brock Faber -- also LA -- and of course as always, I omitted goaltenders from my list.
