Yet after Matt Stover kicked a game-winning, 46-yard field goal as time expired yesterday, there was a level of amazement as the Ravens celebrated a 26-23 victory over the Arizona Cardinals at M&T Bank Stadium.
After the Cardinals tied the game at 23 with 1:50 left, Boller went 5-for-5 for 32 yards on the final drive, converting two third downs and putting the Ravens within range for Stover's 13th career game-winner.
Watching Stover's kick split the uprights on one of the end-zone stadium screens, Boller let out a scream and pumped his fist high in the air toward the sellout crowd of 71,372.
"I love that situation," said Boller, the often-criticized former first-round pick who finished 8-for-10 for 83 passing yards. "I like the pressure."
The Ravens improved to 2-1- one game behind the undefeated Pittsburgh Steelers in the AFC North - albeit in an unconventional way.
Boller replaced starting quarterback Steve McNair with 12 minutes left in the game and the Ravens holding a 23-13 lead.
The move surprised the offensive players, including Boller and McNair, who said his injured groin was "fine." But Billick indicated that he pulled the quarterback because McNair was "favoring" it.
"Rather than push it over the edge and turn it into a two-to-three-week [injury], I think he's fine," Billick said. "We're lucky to have Kyle there."
McNair never told Billick there was a problem with the groin, and the switch at quarterback was announced during the game as a coaching decision.
Asked whether he would be ready to start Sunday against the Cleveland Browns, McNair said, "Of course I'm good. I could have finished the game."
McNair then added: "It was the smart thing to do. We were up, and I think we wanted it to rest and heal. In this league, it takes two good quarterbacks to go where you want to go."
In three quarters, McNair completed 20 of 27 passes for 198 yards and one touchdown. He led the Ravens to scores on four of seven drives.
When Boller came in, he had two forgettable series. After a three-and-out on his first possession, Boller was sacked on third down to take the Ravens out of field-goal position on his second series.
On the last drive, Boller took over at the Ravens' 20-yard line with three timeouts and 1:50 remaining in the game.
"I have a lot of faith in Kyle and what he can do on a football field," receiver Derrick Mason said. "He proved it last week, he proved it last year when he had to come in and he's going to continue to prove himself. Whenever Kyle comes in, it's never a panic in the huddle."
Boller converted a third-and-two with a 5-yard pass to Mason and then found tight end Todd Heap for 12 yards on the biggest and roughest play of the game. Going over the middle at midfield, Heap leaped in the air and was hit in the head by the shoulder of 230-pound safety Adrian Wilson.
After lying on his back for a few seconds, Heap needed help walking off the field as the referee marked off a 15-yard penalty for unnecessary roughness.
