DJ Bean has been doing some sleuthing around, and just put this on twitter:
Per a source, Bruins are moving on term re Eriksson. Offered three years in December. Most recent offer was longer. Ongoing discussions.— DJ Bean (@DJ_Bean) February 25, 2016
Apparently, Cam Neely was on the radio before that, and said they haven't heard back on that offer:
Cam Neely tells us Don Sweeney recently sent offer to Loui Eriksson camp "the other day" but hasn't heard back. #Bruins— James Stewart (@IAmJamesStewart) February 25, 2016
Eriksson is, of course, in his age-30 year. Longer than 3 years would mean that his contract would extend through his age-35 year in 2020-21. For comparison's sake, Patrice Bergeron is also in his age-30 year and is signed through 2022. Not that Loui Eriksson is necessarily as good as Bergeron, but his game is based on a skillset that should be able to last at least until he's 35.
If the Bruins do sign Loui Eriksson to a 4+ year deal, he'll obviously be unavailable for trading. The Bruins likely want to either move or sign him by Monday's trade deadline.
