Lindgren is really the answer here although I think the cost in terms of futures will be more than people expect. He's having a stellar season for the Caps behind a poor team and he's signed for $1.1 million through next season.
That kind of performance to contract value for another year and a half is worth its weight in gold. Even if he comes back to earth that is a fine contract for an above average backup. But if he keeps playing like he has this year and in his previous stints in St. Louis? It's a bargain contract for a good starter.
The Caps aren't going to give him away but they are stuck with Kuemper's big contract even though he's been significantly worse than Lindgren and they have another unheralded gem in Stevenson due in the next year or two.
Frankie will be gone next year so $4.5 million combined for George and Lindgren is very doable.
