He brought him in as the starter during FA in 2005 after McCown flamed out in 2004. He started most of 2005, but was pretty bad then we drafted Leinart. But Warner stayed the starter in 2006 until Leinart eventually replaced him around Game 4 or 5 of his rookie season. 2007 was the year he started his incredible comeback when Wiz started rotating QBs in the middle of games and then totally took over after the collarbone injury.Denny brought him in to be a backup to and mentor McCown. Warner was pretty much backup until 2007 when Leinart had a collarbone injury.
