KANSAS CITY, Mo. -- Matt Moore was living a comfortable life helping to coach his former high school's football team in California, but in late August the Kansas City Chiefs offered him a job as the backup quarterback to Patrick Mahomes.
One of the significant reasons Moore accepted after a year away from the NFL was the chance to play for Andy Reid and his proven ability to develop quarterbacks.
"It was a huge factor," Moore said. "You look at his history with quarterbacks, with offenses. ... It's a huge opportunity. It's a rare opportunity."
The Chiefs haven't announced a starting quarterback for Sunday night's game against the Green Bay Packers at Arrowhead Stadium, but they're preparing Moore as if he will replace the injured Mahomes. If Moore indeed plays, he will be trying to help Reid improve what has been a remarkable record of winning games with backup quarterbacks.
With the Chiefs, Chase Daniel was 1-1 but only a missed field goal attempt in the final seconds kept him from being undefeated. Nick Foles was 1-0 as a starter in Kansas City. Mahomes was 1-0 during his rookie season.
Going back to Reid's time with the Philadelphia Eagles, many of the backup quarterbacks had a winning record in replacing the injured Donovan McNabb. Jeff Garcia was 5-1, A.J. Feeley 4-3, Koy Detmer 2-1.
Going with a backup QB doesn't mean defeat for Reid.
"I don't think we'll have to change the whole offense, but definitely, sure," Reid said of changes to the game plan against the Packers if Moore is the starter. "That's part of being a coach and knowing your players. You want to put them in the best position for what they do ... so you can utilize those tools there.
"It's not going to be exactly like Pat. They're all different. ... We've got enough in the offense where I might be able to get [Moore] a couple of plays."
Feeley, who started for Reid in two different stays with the Eagles in 2002 and 2007, said Reid is better at tailoring his game plans to accentuate a quarterback's strengths and minimize his weaknesses than any coach he played for in his other two NFL stops.
"I wouldn't say he necessarily makes playing the position easier, but he puts every quarterback in the best spot to be successful," Feeley said. "That's not always the case for coaches around the league or schemes. He's just got the knack for getting you in the right play so you're not behind the eight ball to begin with.
"He's good at giving guys the short passing game and easier reads to kind of get into the flow of a game. That's helpful to any quarterback but really to a quarterback who hasn't played a lot recently. I've been on other teams where it's a vertical passing game and it's your job to make it work without a lot of tutelage on what they really want. With Andy, you go into it prepared."
Feeley said Reid gives his quarterbacks an unusual amount of input into the game plan. He said the day before every game, Reid calls the quarterbacks into a meeting to collect their favorite plays from the game plan for various situations: first downs, goal line and short yardage, third down, red zone.
"Andy will meet with Matt during the week, probably on Saturday morning, to kind of go over what he likes in terms of the game plan." Feeley said. "I imagine if there's a question in the game of running one play or the other, knowing what Matt is more comfortable with, he will call that one."
Feeley joined the Eagles as a fifth-round draft pick in 2001 but had to start five games the next season because of injuries to the Eagles' other quarterbacks.
"When I first had to play, I was young and really inexperienced," Feeley said. "The first couple of games he might have called the game to that and allowed me to have success and allowed him to see if I could handle it. The first game or two were run-heavy in terms of the game plan. He didn't know if I could handle it. As we went on, he opened it up to the full offense knowing I could handle it.
"From the point I was made the starter, Andy didn't flinch. There was no hesitation. He didn't waver. There was no hand-holding. He told me he had expectations for me just like he had for Donovan but that he would help me reach those expectations, just like he did for Donovan."
His first genuine playing time came in last week's win over the Denver Broncos after he replaced the injured Mahomes.
"There wasn't anything too big [for Moore]," offensive coordinator Eric Bieniemy said. "He played hard and he made good decisions. He'd like to tell you that he probably could have been better in certain situations. But the thing I liked is he continued to hammer away. That was the important thing."
If he plays against the Packers, Moore should benefit from having more than a full week -- the Denver game was on Thursday night -- to prepare.
"It's hard to do really the whole thing he's done here just coming in late to us ... and then asking him to pick up this offense, which is complicated," Reid said. "And then it's hard to be a relief pitcher. But he's done it before. There's a certain way to prep for that and he understands that and it paid off for him."
