But it sure can make the next week a bit more pleasant.
Such is certainly the case for Painter, who on Thursday night responded to a difficult week of criticism and questions with a near perfect performance in the Colts' 34-21 preseason loss to the Buffalo Bills at Rogers Centre in Toronto, Canada.
Painter, a sixth-round selection in the 2009 NFL Draft from Purdue University who moved into the backup role this past offseason, had thrown three interceptions in a preseason-opening loss to San Francisco the previous week.
On Thursday, he completed 5 of 6 passes for 97 yards and a touchdown.
"Compared to last week, we were taking care of the ball a little better," Painter told Colts Radio. "We were getting completions. When I was out there, we did some things well - again, we still need to fix a few things, but we had a nice drive and taking care of the ball was definitely a positive.
"I think it was just getting into a rhythm early, getting some completions. We made a few plays and let some things happen. That naturally calms you down a little bit."
Such a response has been the norm for Painter this week, who despite being criticized by media and fans answered questions on his performance against San Francisco with striking poise. Colts coach Jim Caldwell said throughout the week he liked Painter's mental toughness, and most importantly, Caldwell said Painter remains the No. 2 quarterback.
The Colts' actions on Thursday supported that stance. Painter again replaced Manning in the first half, and in the second half, it was rookie quarterback Tim Hiller - and not last week's third quarterback, Tom Brandstater - who replaced Painter.
Painter on Thursday replaced Manning late in the first quarter, and early in the second quarter, and led a two-play, 81-yard drive. He passed 38 yards to wide receiver Taj Smith on the first play, then found Smith open down the right side for 43-yard touchdown on the second.
"You kind of have to take advantage of these opportunities," Painter said. "You might not get too many during the season, but getting the experience can certainly translate should anything happen during the season. Just continuing to get better and move forward is really the biggest thing."
