It was just as much if not more on Allen.
He wouldn't play Baun. What can Loomis do in that situation? We got an extra year of an aging Davis instead of an All Pro Baun.
Allen called Hendrickson an effort player. You think that sounds like an endorsement to re-sign a player? Allen had control over the defense when Payton was coach, so I doubt he lobbied hard to keep Hendrickson.
