My first thought is that when these two teams struggle at quarterback, they really struggle at quarterback. Those lists of 1 and 2 year guys are a horror show.
Aside from that, I feel like the Raiders are weaker than they appear. 15 pro bowls? Lamonica was before my time so I can't comment there, and I never thought of Stabler as a world beater. Gannon was a painful fluke, going to four pro bowls beginning the year after he left the Chiefs. Shaking my head over that. But I look at that list of quarterbacks and I'm not seeing anything above average in total. I'll rate them average to respect the pro bowls, but even then that seems generous.
On the other hand, the Eagles are stronger than their pro bowl stats indicate. 34 years of McNabb, Jaworski, Cunningham, Snead, and the Dog Murderer seems like a really good record. Oddly, Jaworski only got 1 pro bowl and Snead was in multiple pro bowls, but not for the Eagles in this time frame. Now, when they're bad they're shockingly bad, as evidenced by the sheer number of Detmers on their list, but I still think they're very strong.
In a funny note, I was looking up pro bowls and was shocked that Mike Boryla was in one. I didn't remember him as a top player, and in his pro bowl year he had 996 yards passing, 6 TDs, and 12 interceptions. Read his story here:
