Yes, absolutely. With only two variables, you’re missing out on a lot, and your observation is one of those factors.

SRS measures team quality at the end of last season. Wk 1 Cover measures performance over expectation. However, teams might improve their team quality in the off-season in ways that lead to an improved point spread. Would Denver have been favored by 2.5 points over the Steelers without Manning at QB?

Could this omitted variable bias your estimates in any way?
