"One look and you couldn't help but feel sorry for that poor back tire.

A golf cart shot past at the Farmers Insurance Open patrons with Chargers guard Kris Dielman testing its weight limits. Well, him and a couple other similar-sized guys.

Dielman said he was "doing great" after a concussion prematurely ended his season and left him to contemplate retirement. He has yet to decide if he'll play next year but hinted he hoped to soon.

Any other clues? Leaning one way or the other?

"Not really,'' he said. "We'll see.''

The Chargers need to know, as their offensive line remains the biggest red flag flapping in these delightfully warm January breezes.

Not only is Dielman's future uncertain, but center Nick Hardwick, another Pro Bowler, is also pondering retirement. And even if he does decide to continue playing football, Hardwick is a free agent who can sign with any team."
