Well, this is what is written...
Each team may have a maximum of 44 players, including 3 players who shall be identified as quarterbacks and 41 other players, of whom not more than 20 may be international players.
...the way I interpreted this, was that each team had to have 3 players identified as QB, whether they are QB's or not, but they had to have 3 listed on the roster. Not saying that I am right, just how I read it. I guess we'll see when Hamilton posts their lineup for game day.
