Currently, we have a 12 team league with 18 roster spots. You must start a QB, 2RB, 2WR, TE, K, DST. Thinking of adding a 3rd WR or flex player for next year. Some have argued that if we change the format to another WR or flex, we need to limit our roster spots. I've also heard of other leagues that allow flex player to be a QB - I'd rather it be RB or WR. Any thoughts on the pros and cons of 3rd WR or flex player? Thanks.
