Should Chargers trade for a potentially part-time Trent Williams?

The Chargers need to consider all options with Russell Okung dealing with an undisclosed injury. Is a Trent Williams trade worth it?
The Chargers should be considering all options with Russell Okung, the team’s starting left tackle, dealing with an undisclosed injury:
Lynn provided no update on LT Russell Okung, who missed this week's minicamp with an undisclosed injury. The Chargers do not know if Okung will be ready for training camp in July.

Apparently, the Chargers are unsure (which really means unwilling to disclose) what the duration of Okung’s absence will be. First they were hopeful the veteran could return by training camp, and now it’s unsure if he will return by then.
The Chargers should only express interest in trading for or signing a left tackle if they feel Okung will be out for an extended period of time. Sam Tevi is not the answer at potentially the second-most important position on the roster, and he should be focused on nothing but manning the right tackle spot. No other tackle on this roster is capable of starting, unless Forrest Lamp feels he can. And even then, that’s a big unknown. The Chargers do not want unknowns facing
- Week 1: Colts
- Week 2: Lions
- Week 3: Texans
- Week 4: Dolphins
- Week 5: Broncos
- Week 6: Steelers
- Week 7: Titans
- Week 8: Bears
to open the season. The team was one game away from having a first-round bye last season, and must do whatever it takes to ensure they skip the Wild Card Round and play the New England Patriots as late as possible, if at all.
They need a leader, a veteran, and a good starter; who better than Trent Williams, who reportedly is unhappy with his current contract?
