Fade the Colts the rest of the season?

[Easy E]

So, how will the public perception of 13-0 affect the spreads for the Colts the rest of the year?

Sun. Dec. 18 1:00 p.m. ET Chargers
Sat. Dec. 24 4:15 p.m. ET at Seahawks
Sun. Jan. 1 1:00 p.m. ET Cardinals

If Dungy follows through and takes resting for the playoffs over perfection, will the early Colt lines be the best ones to fade?
The next two games are big ones for the opponents, though the Seahawks might not need the game if they clinch NFC home field (only the Bears and Bucs can match/beat their NFC record) and the Seahawks can fall back on the last game of the year against the Packers to clinch HFA. Of course, the Colts will be a home game for the Hawks.

Any strategy that we can plan for? We can discuss the Seahawks next week, if they win and the Bears and Bucs both lose.
