I'd say it depends on alot of factors: how many teams, what else you have and what others are keeping, etc... if say its a 12 team league and rodgers, brady, brees get protected, you have 9 teams fighting for a qb. of top roethlisberger, eli, stafford and most likely someone like rivers go before cam. so thats 4 more players gone, 7 of 12 teams already now have a qb. do you want to protect Cam or protect a good RB you already have on roster and get cam in round 2 or so of draft?
