The Riced looks pretty solid, although I'll look it up later to be sure.

As far as the Blanda goes, however the photo having been taken during a preseason game doesn't automatically translate to ONLY having been worn in the preseason. It could well have been worn during the regular season, as well. Back in the mid-1970s, just like in the other major team sports, NFL players didn't have a locker full of jerseys. They probably had 2 of each style, maybe 3 and that was it. Even the superstars didn't get supplied with a high quantity of jerseys then. Before I'd give up on the Blanda I'd suggest checking more photos from 1975 in the regular season to find, if not a pure photomatch, at least a style match focusing on the NOB font used. Good luck.
