My starting roster consists of 1QB, 2RBs, 2WRs, 1 Flex Position, which can be either a RB or a WR, 1TE, 1Kicker, & 1DEF / ST. Shown below is my entire team's roster:

I am torn on who to start at the RB position especially. If you can please give me your opinions on who you would start & why and advise what changes you would make to my starting roster, at any position, would be greatly appreciated.

Thank you,
