NEW YORK -- With so much wheeling and dealing, maybe the NFL draft should move to Wall Street.

Minutes before Andrew Luck and Robert Griffin III went 1-2 to the Colts and Redskins on Thursday night, the draft at Radio City Music Hall turned into a deal-a-thon.

Through the first seven picks, only Indianapolis kept its original draft spot, and a total of eight trades were made in the first round.

The Browns, Jaguars, Cowboys and Eagles all traded up to get players they coveted. The Vikings dropped a spot and still came away with the guy they wanted.

Credit the rookie wage scale for so much buying and selling so early, with general managers making last-minute moves knowing that extravagant salaries for top picks have been replaced by a compensation plan.

Before NFL commissioner Roger Goodell opened the draft, Minnesota swapped its No. 3 choice for Cleveland's No. 4 pick, with the Vikings also getting fourth, fifth and seventh rounders.

After the Browns went for Alabama running back Trent Richardson, and before the Vikings took tackle Matt Kalil, Florida neighbors Tampa Bay and Jacksonville swung a deal.

Cleveland coach Pat Shurmur said the Browns were convinced a team would leapfrog them to take Richardson, so they pulled the trigger on the 4-for-1 trade.

"Unfortunately, we had to make a little trade to secure the pick," Shurmur said. "We knew as we went through the process that he was our guy and so we did what we had to do to secure it. We had pretty good knowledge that there were teams behind that wanted him as well, so we gave up a couple of picks to make sure we got him. We're thrilled a bunch about Trent."

The Jaguars moved up to No. 5 from No. 7 and grabbed wide receiver Justin Blackmon.

The Buccaneers, at No. 7, chose Alabama safety Mark Barron, and also acquired the Jaguars' fourth-round choice.

"It just goes to show you that anything can happen," Blackmon said, referring to the Jaguars going after him.
