I think it depends on the mental state of the Colts at this point. After being beaten by San Diego to end the streak and keeping their skilled position players healthy in the loss to Seattle, followed by the emotional loss of Tony Dungy's son and then winning the last game against Arizona for the coach, plus a two week layoff, not really certain how football sharp the Colts may be in the first playoff game. If the Steelers are sharp enough to beat the Bengals and the Colts are not crisped, an upset is possible. As for the line, probably Colts -7.
