1st goal is a perfectly placed shot at top corner, sure Rinne can stay up rather than go to butterfly but what happens after the initial save or if the puck is deflected by Benn who is ALL ALONE in front of the net? Goaltending is often a game of chances, it favored Rinne something like 80-20 this time for the first shot, but sometimes even with better odds you just lose.
2nd goal is a free shot for Radulov of all people from the best goalscoring sector in the game. It's also way harder to determine pucks trajectory if its not coming flat at you. I'd ask what the hell were the D (#14 and #33) doing in that situation because BOTH of them tunnelvisioned on the Dallas forward (#20) so the goal is more on those two than Rinne.
3rd goal is a big rebound but its a tough angle to play when its a hard shot, it also depends what kind of pads you are using, if Rinne was using softer pads (Vaugh Velocity for example, or the ones Saros uses) the rebound would actually direct in front of him more than to the side. This is something that people who do not play goalie often overlook since its niche information. Anyways, backchecker has lost his man who gets to put it into empty net.
4th goal a shot from nearly the same spot where Radulov scored goal #2. Rinne played a tad too deep in his net in this.
Thats 2 goals from prime slots, 1 big ass rebound and a lost game of chance. Explain to me how 3 of those 4 are on him when team defense loses coverage 3 times out of 4 goals?
