Eagles 3rd-round rookie QB Nick Foles has had an impressive preseason and appears to have bypassed Mike Kafka for the #2 QB spot.  Starting last night's game against the Browns in place of Michael Vick, Foles completed 12 of 19 passes for 146 yards with 2 TDs and 1 INT.  For the preseason, he's completed 63% of his balls and averaged a juicy 8.9 yards per attempt.  He's tossed 6 TDs vs. just 2 INTs.  "He's confident," WR Jeremy Maclin said of Foles.  "I think he's very talented and as long as he stats confident and stays poised, you'll continue to see him have good games."  Foles obviously isn't a threat to Vick's starting job, but he does have the look of Philly's QB of the future.  He's a worthwhile long-term stash in deep dynasty leagues.  Foles' emergence is also nice insurance for Eagles' pass-catchers in the event of another Vick injury.
