Funnily enough i was thinking if you pay him Conley's money then its a non issue but DM is about to get a bump and the maths goes beyond me. Id think 4 at 100 or five at 125 would be perfect, plus incentives.
Meh, offering him his current money (25M per year) after giving Don his deal (5/163-195 depending on qualifiers) feels pretty insulting ngl.
