100% agreed they pulled the plug on Warner too early. For everyone who is saying to give young QB's a few years to mature, while losing many games, not giving Warner a season to let his thumb heal seems odd. Favre went through it.
Also, many forget that Orlando Pace held out that year and the first few games had poor o'line play, then add in the thumb injury and Warner was fumbling when sacked. Plus Warner was treated like glass that year and held out of preseason. Bulger comes in after playing all preseason and was more ready. Fast forward to week 7 or 8 and the Rams are about to play the hapless Falcons on MNF. I have no doubt Warner would have also put up a 40 burger on them, and got his job back.
