A guy offered me a 3 good players for cmc

A league mate offered me Amon-Ra St Brown, Alvin Kamara, and jjetas for cmc. Should I take. 1 qb 2 rb 2 wr 1 flex 1 te

Current team: Qb: Lamar Jackson Rb: cmc kyrene Wr: Ceedee, Micheal Pittman jr Te: kincaid Flex: Gibbs or Devonta smith

I think I should take it but I’m not sure about giving cmc cause he’s saved me so many times
