I love Severson as a player and think he is greatly underrated but given he will be 29 at the start of his next contract and who we have, I have to agree with you.letting him walk for free would be a mistake.
You have two other RHDs signed longterm and you just picked one 2nd overall who might make the team. He should be moved IMO.
5 more years at $4.4
I think we likely keep him because I think this is an important year for Fitz and making progress as a team, but the right decision is likely trading him.
