I have seen Colts linemen in the Fred Kail series, but nothing in that series that really resembles Johnny U as far as I know. (Unless Johnny really let himself go in the offseason!)
As a long time figural collector, I have never seen anything, other than the Unitas Aurora kit, that featured any other players. Aurora also put out a set of two full teams of small figures that were to be customized to any teams you wanted them, so of course someone could have done a Colts/Giants set out of those. Other than that, I guess I haven't seen anything else like what he refers to, so if you do see some at a yard sale, pick one up for me too!
