But it's changing opinions on a 10 game sample rather than what your opinion is over the previous 40. Small sample or not, it's still a case of placing more importance over 10 games rather than the previous 41.
Let's look at it the opposite way. If someone believed McDavid was the superior player at Game 41 for each guy, then McDavid went on to score 5 points in the past 10 games, they shouldn't then use those 10 games to switch their vote to Crosby.
So then why would someone who thought Crosby was the better of the two when comparing their first 41 games suddenly feel McDavid is now the superior player after 10 extra games?
Also, this idea it's "bias" on my part (not you who suggested it) as a defense of Crosby are missing my entire point. I don't give a shit if someone chose McDavid. If you feel he's the superior player, then vote for him. What I'm saying is though it shouldn't be entirely because McDavid got red-hot over the past 10 games. Likewise, if McDavid had gone ice-cold over those 10 games, you shouldn't suddenly think Crosby was better based on McDavid's pace falling off.
