I'll be honest, I never thought Rantanen would be THIS good, but his development trajectory has been like a rocket to the moon. I Can't imagine he will maintain this forever but I also think he will be a very good player for a long time.
I was skeptical Colorado would turn things around, but they actually look like a team that could be a big time power again within the next couple years. They have a kid coming in, Cale Makar, who is an unreal offensive defenseman, I would say he reminds me just a little of Drew Doughty or Karlsson on the offensive side of things. he's very talented. Then, depending how awful Ottawa does this season, the Avs could be adding another big time talent.
You guys know all the other pieces they have, so that said, I think Rantanen has some more upside but I would hold a bit more and see if Colorado's team success and additions of other young stars boost their popularity and winning ways.
