I've met Mark Murphy twice, both times while touring someone through the new Hall of Fame. Seems like a nice guy to me. Nobody forces him to come out and interact with Joe Public.
The thing about Starr was, well, he was freakin' Bart Starr! We loved him even if he really had no coaching experience. Dan Devine treated him like garbage, and left him a bare cupboard. You combine those things and it's easy to see why Bart got a longer leash than others.
As to the ketchup thing, to each their own. Nobody has any business telling someone else what they can and can't put on food. In my world, brats & sausages generally get mustard and hotdogs get ketchup. It works for me. Now.....
Back in 1999, a group of us went to the Wisconsin/UCLA Rose Bowl game. We had the UW package, which included pep rallies and tailgating. At one pep rally next to the hotel, they had all kinds of food and beer. I went to get a brat, took a bite, and uncontrollably spit it out right onto the ground. The serving lady had a look of horror on her face. I asked her how they cooked these things, to which she replied that the '...boiled them in pickle juice.' I shook my head and left (after picking up my spittings).
That same trip, they had a pep rally on the Santa Monica pier with the marching band, etc. I still have the news paper clipping from the next morning. It made the news that the "thirsty Wisconsinites" quickly descended upon all of the bars along the Santa Monica pier after the pep rally ended. They drank so much beer that every bar ran out of beer. Those bars started calling bars up and down the coast, begging to borrow kegs of beer to satisfy their thirsty customers. The article noted that most bars in Los Angeles only carry limited beer offerings compared to those in Wisconsin, and thus were not prepared.
