Peyton Manning will draw a ton of attention in Denver. Similarly, the Mark Sanchez-Tim Tebow dynamic will pin a spotlight on the Jets quarterbacks.

But it's easy to see where Chad Johnson (no longer Ochocinco) has the biggest bull's-eye on his back.

Not only did he get run out of New England after one unproductive season, but the new Dolphins wide receiver has been quite vocal this summer about his ability to recapture his Pro Bowl past.

If he's right, the Dolphins will have found their low-budget replacement for the traded Brandon Marshall.

If Johnson, newly married and back in his hometown, is wrong, well, this could be the end of the road for one of the NFL's loudest mouths.

Spotlight on Manning

It would be unfair to look to any of the promising first-round picks to immediately show they are as good as expected. Andrew Luck and Robert Griffin III playing in controlled settings against teammates won't tell us anything. They have to prove themselves later, against others.

But we're already aware of what Peyton Manning, in his first year quarterbacking the Broncos, should be able to do. So the throws he can or cannot make during drills will be telling. Manning endured long rehab from serious neck surgery and a painful break from the Colts to reach his late-career second act. He already has proved he's one of the greatest passers ever, but no player will be more scrutinized.
