You can still put Richardson on your squad since he's on the final roster (even if it's practice squad).
And pestilence, I have the same problem with the kicker. I think it's too late to re-do our drafts, and there's no way to pick one up. Unless people can come up with a reasonable solution, I think you and I are going with Scrubby McScrub as our kicker this year.
