A nice cyclical BCS team like Washington, Boston College, ASU, MSU, Iowa, etc. Nothing more, nothing less.
How cute of you to pick five programs that in the last 20 years are distantly behind Wisconsin. Washington has had some good runs in the 80s and 90s....so that's fair. Michigan State hasn't seen Wisconsin's success since the 50s and 60s (even more recent than Minnesota). BC, ASU and Iowa have never had a 20 year run like Wisconsin. Here are the numbers between your choice of programs in these 20 years, just for fun:
