"And if we have to punt, we'll treat that with an attitude like it's a turnover."
At a press conference to introduce the Bears' new coordinators Thursday, Shea was more specific about his plans and admitted he'll have to adjust to his talent.
She plans to turn the Bears from a run-oriented team to an offense that he said will throw "60 percent of the time on first down."
"With that thought, your passer has to be a 60-percent completion percentage passer on first down or better," Shea added.
Shea said he met the past week with Bears second-year quarterback Rex Grossman and has been impressed by what he's seen on film. He thinks Grossman can be that 60-percent first-down passer.
"We've got a quarterback who's got a very efficient release," Shea said. "He slides in the pocket with a lot of poise. He throws with somebody right in his chin, and you don't find that too often from a first-year player, as Rex has been as a rookie."
In his first meeting with Grossman, Shea thought he detected a competitive fire.
"He's got that look in his eye," Shea said. The idea will be to produce 52 positive yardage plays in a game, Shea said.
To do it, Shea said there will be a great deal of trap blocking in the running game, extensive use of draw plays, numerous misdirection screen passes and passes designed to break big gains downfield.
"This is a great offense to control the flow of the game and score points," Shea said.
The big question the Bears must answer in the off-season prior to the draft is whether Anthony Thomas can become a versatile player like Priest Holmes was in Kansas City for the offense.
"We do have a lot of misdirection flow to our offense, so if he can stop and start and get restarted in a giddy-up then we've got ourselves a style of runner that would be very, very productive," Shea said.
Ultimately, Shea said, the first year of his offense is going to involve adjusting to his talent until the players who fit his system surface or are developed. It's impossible to force talent on the team now to do things they're incapable of accomplishing.
"I've been down that other road and it doesn't work," Shea said.
