As the Vegas Golden Knights’ success gradually goes from shocking to accepted, there’s still the question of what this team might look like next season and beyond. Such questions are only natural when you consider all the key players who still need contract extensions. Golden Knights management is chipping away at those questions regarding their defense in 2018-19, particularly this week. On Monday, the Golden Knights signed local favorite and rugged defenseman Deryk Engelland to a one-year extension worth $1.5 million. (That deal includes $1M in potential performance bonuses, according to Cap Friendly.) One day later, the team announced a two-year extension for Jon Merrill (pictured). The deal is for $2.75M overall, so it will make for a $1.375M cap hit in 2018-19 and 2019-20. The Golden Knights now have five defensemen on their current roster who are signed through 2018-19, if not longer: Engelland, Merrill, Nate Schmidt, Brayden McNabb, and Brad Hunt. McNabb is locked up the longest, with a $2.5M cap hit kicking in next season and expiring after 2020-21. The most interesting remaining defensemen to sort out are Colin Miller and Shea Theodore, both pending RFAs. The Golden Knights have been buying up blueliners at bargain rates, but Theodore and Miller could be tougher nuts to crack contracts-wise. (Two UFA defensemen Luca Sbisa and Clayton Stoner on IR.)
