Thanks for the link, Mickey. There is an interesting story there, though it is a shame it was obscured by that particular author's "style."
Actually, Chandler, the all-injury year was 1968, whereas Powell and Flores arrived in March 1967.
The 1967 season is interesting in itself, because it was an excellent example of how quickly a veteran team can collapse even without injuries. Heck, the Bills even added an aging Keith Lincoln to a squad that had won the Eastern Division in 1966, so some people thought they would be back on top. But the rest of the team, Kemp especially, began showing their age. They lost a lot of bad luck games, and fell to 4-10.
I am betraying a bias bequeathed to me by my dearly departed father, but he always said that trading Lamonica was the killer because he was several years younger than Kemp and it would have been better for the team, if they had to move one of them, to dump #15. As a matter of fact, Flores even beat out Kemp for the starting job (though Jack came off the bench to win the opener against the Jets two days before my birth), which indicated that even Coach Collier knew Jack was nearing the end of the trail. But Kemp was a team leader, very popular with his teammates, and not sleeping with his colleagues' wives... so Daryle had to go.
That Flores and Powell both turned out to be washed up only made the whole thing uglier as the Bills entered a Season of Suck that lasted until 1973.
My apologies for the history lesson. Occupational hazard.
