That's fair. I have previously stated this roster is for Play Now, and Season One of franchise only due to those exact potential issues. Other roster makers may be creating them for the long haul, and as much of a franchise junkie as I am, I'm creating this for the pick-up-and-play folks who want a solid game of football.
This roster makes the studs play like studs, the duds play like duds, and the so-so play as such. You will definitely have a better chance to win with a better roster (as is the case in real life), but there is no bias involved when editing the attributes and in the end it still depends on user skill and knowledge. If you're the Bills, playing smart football, you could beat the Steelers...You'll just have to use the team to it's strengths and minimize their weaknesses. I see what you're saying though. Thanks for the kind words, and I'll definitely be excited to share the first game's results upon completion.
