Only if they add a second or something of equal value. Gryz expires this year, Krug still has some years left.
Krugs powerplay ability alone is worth a contract at 3.25m. His overall ability however, is not worth 6.5m. Outside of puck movement, PPQB (distribution and shot), and his compete level, there isn’t a whole lot to like about the player. Average skater, not gifted physically, not a great defender.
Given where we’re at I’m not sure attaching any kind of pick is worthwhile if it’s full retention. But I also wouldn’t expect anything back outside of a late round pick or a prospect that’s a long shot for him with full retention
