I've been sort of rewatching the Pastrnak
goal, frame to frame, and if anything the bounce they got was on the outer edge of a wide 'fan' of workable bounces.
It came out on a nearly too tight angle, on the goal side of a pretty wide, acceptable spray shot for where the puck could have gone within Pasta's reach. Anywhere from maybe 1 foot closer to Samsonov (max) all the way out to the dot, Pasta is getting it on his flight path to the net.
The way Pasta enters -- not tight against the wall but absolutely to the right of the dot when coming over the blue line, and then chasing straight to the dot -- allows for a pretty wide 'fan' of acceptable bounces that Pasta could pick-up as he charges to the net.
As a right handed stick, able to snatch bounces that might have come back high, wall side, and especially 'starting' his pick-up still above the circle after Lindholm blasted the puck in there, there were some options other than needle threading.
Had Pasta been any deeper he'd have had much less range he could cover for the bounce, but he was coming in high and at speed and was likely to be first to the puck within a pretty wide triangle off those boards.
Lindholm needed to not carrom the puck too tightly against the high side boards, not so much because Pasta wouldn't get it, but that he'd be pulled too wide to attack the net. So short of it riding the boards, anything bouncing back toward the center, but above the goal line, Pasta was getting unless Samsonov could play it.
And indeed, that is probably where Toronto will have their regrets: Samsonov could have aggressively stepped out and just chipped that puck anywhere since other than Pasta, it was four white shirts coming in. Had the bounce been just a little more goal side that is exactly what would have happened, but it could have come back a fair amount up ice and Pasta would have just picked up the pass sooner.
