So you think Jared McCann picks his shots better than Ovechkin, Stamkos or Austin Matthews?
Better? Using that word is a slippery slope.
We are defining "picking shots" as the action of "shooting vs not shooting", not picking locations as in accuracy.
If you watched him this year, you would see that when the shot chance is not "high percentage", he is much more likely to hold the puck or pass it than Ovechkin. So he is definitely more picky about when he will shoot, vs pass, which will always lead to a higher shooting percentage. Note, that does not mean that a player that shoots less is better than a player that shoots more, but the behavior does ultimately effect their sh%. Without other context, it means nothing.
Looking at shooting percentage and formulating an argument about a player is ridiculous without objectively watching them play.
Draisaitl has been a 20% shooter for 4 years. yet a couple of years ago, people here were claiming it was unsustainable. He is smart about when to take the shot, vs when to hold or pass.
McCann is a smart player with a great shot. His high S% is not puck luck.
