Nope. Stabler started and lost all three. He took over for Lamonica midway through that season and stayed the starter for several more years.
The Rams lost three in the mid-70s but had a smorgasboard of QBs. As stated earlier, White started all three NFC losses in the early '80s, but was knocked out of the third one, one (or perhaps THE) reason the skins won or at least won so convincingly (Dallas and White beat them eariler in the year).
Danny White was a much better passing QB than McNabb, but didn't have the running tools McNabb has. Of the two in their prime with good receivers, I'd still take Danny White, who had the best ball fake on play action I've ever seen. Unfortunatly, Danny was never well liked or respected on his team.
