The 2005 Purdue Boilermakers football team represented Purdue University during the 2005 NCAA Division I-A football season. The team was coached by Joe Tiller and played its home games at RossâÂÂAde Stadium. Purdue played eleven games in the 2005 season, finishing with a 5âÂÂ6 record and missing a post-season bowl game for the first time since 1996. Purdue was predicted by many as a dark horse for the Big Ten title, but after a strong 2âÂÂ0 start, lost six straight before rebounding to finish a more respectable 5âÂÂ6.
