Captains boost?

[garyjuehrs_MLBTS]

So if have all the cover athletes and I have David Wright as my captain he gets the boost? Do any of the cover athletes i use get the boost? Just asking so try to refrain from the negative responses.

they always have requirements mate - you gotta read the captain card info - for example the captain Buck card gives certain +'s when you have different amounts of players used from that league - tier 3 gets most boost and you need around 7 or 8 players for example
