No thanks on Lindgren because I feel like he'll be overpaid by a couple mil a season giveth his age. There is no production there from an offensive standpoint and he's not some amazing defensive defenseman. It sounds like the PK was one of his strengths but he took a step back last season.
I read reading this hockey analytics blog on Lindgren and here are some stats that stood out
"According to PuckIQ, Lindgren was a +22, 48.5% for Corsi F% (shot attempts), 45.4% HDCF% (slot chances). Last season, he had 129 shifts in the defensive zone, was a +29, 54% for CF%, and 54.3% for HDCF%.
Lindgren’s other contribution historically has been the penalty kill. This season he logged 200+ mins. However, the Rangers were better at limiting chances on the penalty kill when he was on the bench."
