I was looking at Del Rio's stats the other day:
2003 JAC 5 - 11
2004 JAC 9 - 7
2005 JAC 12 - 4, playoffs 0-1
2006 JAC 8 - 8
2007 JAC 11 - 5, playoffs 1-1
2008 JAC 5 - 11
2009 JAC 7 - 9
2010 JAC 8 - 8
Totals = 65 - 63
He's got stats similar to Kubes (average/below average) except for the obvious spikes where he went to the playoffs - twice in 8 years. According to the latest, he needs another spike really quick or he will be gone after 2011. I'd say Kubes needs a spike pretty dang quick, himself.
Fisher, Kubes, Del Rio..... the AFC South hangs on to their coaches...
