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.

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

Chargers fans welcome the veteran wide receiver back during his first practice since signing a one-season, $8.52 million contract earlier this week.
