The underlying question for me when it comes to the figures is the idea of the 'replacement player' as a concept, and then who that player is in function on this current roster.
Lindgren is, for my money, a better option today than Mackey, Robertson, etc. Had we re-signed Gus, I'd be all over trading Lindgren. Give me a 2nd+ for him all day. But we didn't, and so it's now sort of a Lindgren vs Replacement convo, in which I'll take Lindgren. You can always demote him if other guys play better. Even if we assume Lavi has some weird obsession with using him with Fox (I doubt) Drury can look at the deadline.
Much like I said when we re-signed Strome- for all his deficiencies I do think we are a better team today for having him in the roster. If Lindgren were to go out tomorrow with career ending injury we would be on balance slightly less likely to win the cup controlling for all other factors.
