I've never been much of a Campen guy.
Always seemed to me that Bahk, Sitton, Linsley, and Bulaga came in balling from day one. Lang took off immediately after his personal life calmed down. Feels like a dozen players went on to have long careers after "failing" here. Really the only guy I can think of REALLY improving was Taylor.
I'm far from an online expert and am biased against the guy because I felt his hire and tenure was based mostly on him being buddies with the right people so take my opinion with a grain, or perhaps a dash, of salt.
