I wouldn't be too down on Cam. His upcoming bye is exactly what he needs, and you better believe the coaching staff will hammer him with tapes. Cam is becoming predictable, always looking for the long bomb rather than the first down. He ignored Olsen on several snaps where he was wide open, instead keeping his eyes locked on S. Smith. Expect things to change after the bye.
Definitely pick up Andrew Luck though. He should be owned in all formats, and I see him as a dark-horse to finish the year as a Top 8-12 QB in standard formats. He's shown poise and willingness to lead; he's become a threat in the running game; he plays on a team that I expect to be in plenty of shoot-outs; he was an above average receiving corps.
All signs point to a great year from Luck, and he would be a great spot start during the weeks Newton has a bad matchup.
