tOSU gets my vote... They r always a quality team, but always a few steps away...
The first team that comes to mind is Clemson. I can't tell you how many years the "experts" have said "This is their year to make a title run" yet they never do it. However, for the most part seem to bring in excellent recruiting classes. Have their coaches been THAT BAD?
South Carolina also comes to mind when talking about the SEC teams that always get the pre season "team to watch out for". Granted they made it to the SECCG but good lawd they still managed to lose four games for the year. What is it about these teams (and others) that cause the experts to always predict greatness yet they never produce?
