Keenan Allen walked into Los Angeles Charges training camp Thursday feeling at home, despite a coach and training facility that were new to him.

Los Angeles Chargers wide receiver Keenan Allen is 33 years old, which has naturally led to some fears about his decline. One analyst thinks that decline has already begun.

The Chargers and Keenan Allen are officially reuniting. Los Angeles is signing Allen to a one-year, $8.5 million contract, NFL Network Insiders Ian Rapoport and Tom Pelissero reported. The team announced the deal shortly after.
