Eh, don't agree with this. I don't think Heinen here particularly changes Kapanen's situation or their evaluation of him. If they were just getting Kapanen to have a scoring bottom sixer, then they could have just got one of the cheaper options in free agency, or not qualify him and try for a cheap deal, or something along those lines.
To me the most logical guess at what went down given the money and words is they really like Kapanen, they have a lot of faith in Kapanen, and he was pretty much always coming back bar circs that meant they couldn't.
I also suspect that Hextall doesn't really care if the roster situation is messy as long as he has the 20 guys he likes dressed most nights. I think we saw that with the minimal retention for Rakell last season, and I think we're seeing it again. In fact I think he might actively like it and have deliberately overstocked the team to create competition.
