A bridge deal would be a fair thing to do for both sides, imo.
Hronek as a 25 year old dman that seems to be on the verge of breaking out as a regularly offensive minded dman is worth at least a 2-3 year deal around $6m give or take a million.
If he continues on his trajectory, or stays as productive as he is, then $7m isn’t out of the question and worth the money.
