think human nature changes, so my answer is, yes, great guys then, great guys today. >> if i'm not mistaken, you're the only coach that won three super bowls with three different quarterbacks. do you see that happening again? that's pretty remarkable, joe. >> it probably can, records are meant to -- what i always lead off with, everybody hits me with that, one thing you left out, three great ones.
