Now former Los Angeles Chargers running back J.K. Dobbins has shared multiple messages in the wake of his leaving the team via free agency and signing with the Denver Broncos. One, though, feels like a warning of sorts.

The newest infusion of Bronco horsepower was easy to pick out, beyond his 5-foot-10 stature, because he rarely stopped moving. Or talking.

After signing a one-year deal with the Denver Broncos on Wednesday, Dobbins attended the team's mandatory minicamp practice and worked on a side field. After practice, Dobbins was made available to media members, and he sent a message to his former club, now a division rival.
