Caldwell makes good on comeback promise after bad debut in Denver, offseason snub from Manning

Andre "Bubba" Caldwell canceled his vacation plans after the Denver Broncos' season ended last winter, heading instead to a tattered football field near his home in Atlanta to run routes by himself, ear buds and reflections his only companions.

He was determined to avoid a repeat of 2012, when he caught just one pass and was inactive half the time.

That's why it stung so much when he saw that Peyton Manning had invited only Wes Welker, Demaryius Thomas and Eric Decker to his offseason workouts at Duke University.

Manning explained upon his return to Denver that Blue Devils coach David Cutcliffe, his college offensive coordinator, told him and his brother, Eli, they could only bring three receivers each to the workouts, "so I brought my three starting receivers."
