You know thats not true.
How much has Tolvanen been talked about? 15 points in 19 games since the start of March, and he had 14 points in 16 games in March
How much has Nedeljkovic been talked about? He played 9 games in March. He had a .935 SV%, and took 17 points out of 18 during the month.
How much has Robertson been talked about? He had 16 points in 17 games in March. He has 18 points in 21 games since the start of March.
How much has Shestyorkin been talked about? He's 5th in SV% and 5th in GSAA among goalies who've played 1000 minutes (36 goalies).
As I said, let's just be transparent. One group reports heavily on how their team's player is playing, usually only mentioning the positive. The others don't report very much on how their team's players are performing. That shouldn't confuse anyone about the status of the race. There are other players who could win the award. Others, depending on how one views what's important in deciding the award, might have a better case for it than Kaprizov. It's simply not being voiced in this thread, so some are of the belief that there aren't other rookies having good seasons.
The only times players were being talked about was Stuetzle because he was a very high pick. Smith was being talked about because he's a first round pick. Some were excited about Lafreniere's chances before the season because he was the first overall pick. You simply haven't gotten much reporting on some of the other contenders that weren't high picks or weren't even drafted. The only exception has been Kaprizov because of how excited Wild fans were that he joined their team this season.
Tolvanen has been talked about quite a bit the last week or so. He had such a slow start, he had a lot of ground to make up before he was in the conversation. He's done that and is now getting talked about.
There are 50 references in this thread to Robertson since March 9th, he also started behind the eightball due to Covid derailing the Stars start to the season. By the time he got his first point 4 games into the season on Feb 7th, there were multiple players with 10+ points. It took time for him to get in the conversation.
Goalies are a little bit of a different problem. Ones that were hot early like Lankinen and Kahkonnen have either fallen off or stopped playing as much. There are just so many muddled in a similiar area and they mostly seem to be splitting time.
Like, Nedeljkovic has good numbers. He's also only played 14 games. That doesn't get you into the conversation for the award when there is a forward near PPG. I could see Shesterkin as a finalist if he gets the bulk of the work down the stretch (given how bad Georgiv has been) and holds his numbers, but as of now he hasn't played the majority of the Rangers games.
As far as your last line, the exception isn't Kaprizov because we are excited he joined our team. The exception is Kaprizov because he's a nightly highlight real, that has been consistent all season. If Ty Smith had kept up his scoring, you can be sure Devils fans would be here every day as well. If Robertson keeps it up and closes some of the 10 point gap, Dallas fans will be in here daily as well.
As it is, in 35 games Kaprizov has 10 more points and 6 more goals than anyone else. It's significant.
