The only reason he hasn't moved the team is because he's old, and old people fear change. Buffalo is a broken-in 30 year-old Lay-Z-Boy to Ralph right now and even though he probably knows deep down that a new leather recliner with a built in massager and heater would be better for him, he still can't bear to get rid of his 30 year-old Lay-Z-Boy.
If he were in his 40's-50's and still this cheap, the Bills would have been long gone.
'Eff Ralph Wilson. I'd take Danny Snyder as an owner over him. He may not jack about football and his ego definitely blinds him to his many shortcomings, but at least the little bastard is trying his damndest to win. Ralph just chuckles after each loss and checks to see when the next bingo game starts up.
