That would be ok. Collins, Heuer and Stiever preserves the top core talents. Allows Sox to offer McCann something if he doesn't like offers next year.
Gives us 3 pitching studs this year and next year, with Dunning 4 and Cease 5 is a great rotation for the rest of the year. 2 Young guys will have to compete with Kopech for the last 3 spots next spring. Cease particularly will need to show improvement to keep his spot.
Low salary for Lynn next year gets the OK from JR since RH likely promised no big FA pitching acquisitions in the offseason in exchange.
