Most years we have a guy in the 5-7 range. I don't think that is significantly different than players signing free agent deals. Other than the rivalry smack.
It's funny some of the same posters who claim 9 win seasons are mediocre and being ranked 15-25 is not that big a deal, are the same ones acting like a 5th round draft pick is life or death.
