One of the most prolific, most dangerous, quick-strike offenses in the NFL in recent years belongs to the San Diego Chargers. A running back or lineman may be the only move which will improve this unit.
But just imagine this scenario: Shawne Merriman, the 32nd overall pick (fingers crossed) and maybe a fourth or fifth rounder for Calvin Johnson. That would make the Chargers New Orleans version 2.0. Jackson, Johnson, and Gates jumping for balls thrown deep downfield from Philip Rivers, doesn't get much better than that.
Jackson is 6'5", Gates is 6'4" and Johnson is also 6'5". What team could cover that?
It may be a needless move, with an already excellent passing attack in place and the running game badly needing help, but the current running game would suffice with those weapons to throw the ball to. The Chargers could literally do what they wanted.
With the issue of the first round draft pick, the Chargers' biggest need is run defense. So a 3-4 end or a nose tackle to rotate with Jamal Williams until he retires. Neither of those types of players are of a high enough quality to justify using a late first round pick on.
Drafting an offensive lineman with that pick, would be a good move. Anthony Davis or Bruce Campbell should be available at that stage and Trent Williams could miraculously drop that far down. The offensive line's play will improve with Nick Hardwick's return.
That leaves the Chargers with, realistically, nowhere to go with the pick. There is general consensus that keeping Merriman for the money that he would command, is not worth it with Shaun Phillips playing well and Larry English looking good.
So overall, it really would be worth the risk if the Lions would accept that trade. They probably wouldn't though. It would probably take one or maybe two more picks. Nevertheless, it's worth thinking about because simply, the Chargers would be unstoppable with that passing attack.
