Rasmus situation reminds me a bit of Everett. Both were in big markets and just didn't seem to fit in. Carl in NY and Colby in STL/Toronto
Both came to Houston and just seemed/appeared to be much more comfortable here. Colby has gone from introvert to google wearing maniac who seems like he is having a blast playing baseball again.
Here is a good example that the Astros just tweeted out.

I remember when Everett first arrived, there was some rumbling, probably mostly in the Chron and/or on talk radio, about whether Everett was a good 'clubhouse guy', would he be disruptive to team chemistry, etc. Right away he got some kind of benediction from Bagwell, I can't remember if it was a quote or just some gesture, but after that you knew everything would be alright. They just left him alone and let him do his thing, which was play his ass off, all the time.
And he fucking hated the Cubs. I liked that.
