They should use their best draft capital (and maybe some free agency signings/caps space) to improve the oline and then sign Brady or Bridgewater or Fitzmagick or someone else in free agency. Oline is the only remarkable weakness the Chargers have as a team as far as I can tell
Not necessarily. Swapping with the Chargers and putting themselves behind the Dolphins runs a strong risk that the Dolphins either pick other than a quarterback or trade down with someone who will, because that puts the Dolphins in the five slot with both top five caliber (or even remotely top five caliber) quarterbacks off the board. Not that it isn't still worth doing, since the Chargers would be expected to really pony up to make that kind of move, but assuming they get the player they want anyway is not a really good bet.
I am of a cynical bent, and I'm thinking his lawyers for the battery case he just picked up have told him "you are guilty and nothing changes that, so you need to start thinking about how to find a sympathetic judge at sentencing...and hint, right now there is no such thing." He's getting ready to beg not to go to jail.
His vision problems are pretty well documented going all the way back to college. Bruce Aryans brushed it off once with "well, he can't read the scoreboard but he sees the guys in front of him well enough." But I gotta think being able to see well would have to produce at least some improvement. Wouldn't it?
