ENGLEWOOD, Colo. (AP) - Peyton Manning is only getting better with age.
Those surgical scars on his neck are starting to fade like all those fears that he might never be the same quarterback - or even play again - after his right arm shrank from a damaged nerve in his biceps two years ago.
After attacking his rehab as doggedly as he assails defenses, Denver's 37-year-old quarterback is making it hard to fathom and easy to forget that not so long ago he was missing an entire season and getting fired in Indianapolis.
The four-time MVP is off to the best start of his storied 16-year career.
Driven by last year's playoff pratfall, Manning is putting up historic numbers while directing an imaginative offense that's still working through some growing pains.
