The Denver Broncos face their toughest test to date on Sunday against the Philadelphia Eagles, and they'll need to be at their best. Frankly, the Broncos are better than their 2-2 record, and the Eagles are not quite as good as their record. According to each team's Pro Football Reference page, the Broncos' 'Expected W-L' on the season thus far is 2.8-1.2, and the Eagles' is 2.5-1.5. Well, this troubling problem could totally derail Denver if it does not get solved in Week 5. This could be the formula, and there is no better time for Denver to stop this trend than in Week 5.
