He's a bad defensive player and bad possession player, who doesn't shoot and doesn't generate shots, who soaks up secondary assists.
Rinse, repeat.
I'd argue that overall he is not bad defensively, but when he stuffs up it is monumentally bad and agree about possession.
Do we really care about how much he shoots if when he shoots they go in? Since the start of 15-16 he's 2nd on the team in goals scored. It would be great if he shot more, but for all Kreider's shooting he has 5 more gaols over that span.
What ratio of primary/secondary assists would you like to see (for the record he's at 52% 2ndry assist this year, 38% the year before and 42% the year before that. For comparison, CK is 54%, 28% and 41%)?
You certainly don't have to like Miller, and I agree with the general sentiment that he's a ridiculously frustrating player to watch; but your dislike of him seems to be a bit over the top from time to time
