With four games remaining in the regular season and Eagles injured quarterback Nick Foles healing on schedule, head coach Chip Kelly might face a quarterback decision before a possible playoff run even begins.

After Foles suffered a broken clavicle against the Houston Texans on November 2, Mark Sanchez has stepped in leading the Eagles to a 3-1 record while posting an 89.2 quarterback rating.

Sanchez has shown that he is more than competent in terms of executing Kelly's offense at the highest levels. Against the Dallas Cowboys on Thanksgiving Day, a 33-10 victory, Sanchez authored the first game all season sans an Eagles turnover.

On Thursday Eagles wide receiver Jeremy Maclin joined Mike Missanelli on 975. FM The Fanatic in Philadelphia and talked at length about the differences and similarities between Sanchez and Foles.

"They're different," Maclin said. "They both approach the game differently. Nick gets fired up but Sanchez plays and shows his emotions a little more. I think with the way they run the offense is a little different."

Among the key differences in the way the two quarterbacks run the offense Maclin says, comes down to how they go through their progressions in the pocket.

"They both add a different twist to it but obviously both guys have won games for us this year," Maclin said. "Just the way they go through their progressions. The way they get the calls and everything lined up. It doesn't vary too much, but there is a slight difference."

Sanchez and Maclin both will face what amounts to the toughest test of the season this Sunday against Richard Sherman and the top-rated Seattle Seahawks defense.

In five games Sanchez has thrown for 1,400 yards (7.95 yards per attempt), eight touchdowns and six interceptions. Meanwhile, Foles threw for 2,167 yards (6.95 yards per attempt), thirteen touchdowns and 10 interceptions.

Sanchez certainly has played just well enough to make any decision on who is the starting quarterback once Foles is healthy a difficult one. Fortunately though for Kelly, he likely won't be asked to make that call for at least another game or two.
