A much more relaxed Dirk Koetter addressed the media Monday following the Bucs blowout to Arizona.

A common theme following the loss is that this is a humbling league and they learned that the hard way falling 40-7. Koetter said the defeat in the desert came down to one thing.

"Everything's gonna start and end with the turnovers," said Koetter. "You just can't turn it over five times.  I think there's something like three games in the history of the NFL where a team's lost a turnover margin that bad and been able to win.  You're not giving yourself a chance when you turn it over like that."

"I can already feel it in the weight room, everyone is a lot more intense,ready to go," said Bucs defensive end Noah Spence.  "I don't know if we were like that last week."

Quarterback Jameis Winston was responsible for all five giveaways.  He threw four interceptions and lost one fumble.  He had career high 52 attempts, which was elevated when the Bucs lost top running back Doug Martin to a supposed hamstring strain.

Koetter said they won't know specifics until MRI results come down Tuesday. Back-up running backs Charles Sims and Jaquizz Rodgers shouldered the load in his absence, but Koetter says they can not replace him.

"When you take a top level player out, you usually don't have exactly the same caliber player behind him," said Koetter.  "Even though we are very high on Charles Sims, but it definitely hurts ya.  That's the NFL."

Defensive End Robert Ayers and tight end Luke Stocker also went out with ankle injuries.  

Koetter also addressed Jameis Winston and Vincent Jackson's lack of chemistry. He said their precision isn't there and is something they need to straighten out soon.

Koetter is hoping it's in time for their home opener Sunday against the Rams. L.A. is the only team that hasn't found the end zone yet scoring just 9 points in the first two weeks all via field goal.
