Even though most online leagues don't have a salary cap, building a roster for an offline franchise is a lot like a real NFL team. You can only have x amount of studs on your roster, and the rest of your postions are going to be filled by 70's and 80's rated players.
So, in your opinion, which positions on the roster do you think it's vital to have a "stud", and which positions can you sacrafice overall ability as long as they have certain attributes. And for those positions, can you give the critical factors you look for ? Like maybe a low rated safety with good speed and catch.
