Andrew Luck and Robert Griffin III headlined the 2012 NFL Draft at Radio City Music Hall Thursday as expected but after that a flurry of wheeling and dealing marked the first-round of the prime-time event. The Indianapolis Colts kicked off the annual draft party that filled three balconies at the venerable Manhattan theater with fans decked out in their team colors by taking Luck, the celebrated Stanford quarterback, with the No. 1 pick. After the Washington Redskins followed, as expected, by selecting Griffin, the Heisman Trophy-winning quarterback from Baylor, a string of four trades shook up the first half of the proceedings as teams jockeyed into position to nab the players they coveted. Four more trades, including two made by the New England Patriots to move up, highlighted the second half of the draft, which is the lifeblood by which NFL teams restock their teams and address weaknesses. The top of the draft offered no suspense as Luck and Griffin went one-two as undisputed top of the 2012 draft class. Luck, considered one of the most polished quarterback prospects in recent years, will be taking over the reins of the Colts' offense from four-time NFL Most Valuable Player Peyton Manning. “Yeah, Peyton Manning, arguably the greatest ever,” Luck said about the 11-time Pro Bowler, who signed a five-year, $96 million deal to play with the Denver Broncos after the Colts decided to embark on a rebuilding plan. “He was my football hero growing up. I realize you don't really replace a guy like that. Those shoes to fill are huge.” Luck was handed a No. 12 Indianapolis jersey, to match the uniform number he wore at Stanford. Griffin, popularly known as RG3, is a running threat as well as a strong-armed passer and edged out Luck as winner of the Heisman in December as the top US college player. The Redskins so coveted Griffin, they traded their No. 6 overall pick along with a second-rounder this season and No. 1 picks in 2013 and 2014 to the St. Louis Rams in order to move up to No. 2 in the draft so they could claim him. After the selection of those two blue chip quarterbacks, who will be linked as quarterbacking headliners of the 2012 draft, a flurry of trades followed. The Cleveland Browns swapped picks with the Minnesota Vikings to take Alabama running back Trent Richardson with the third pick. Minnesota, enriched by added picks in the fourth, fifth and seventh rounds, took offensive tackle Matt Kalil of Southern California. The Tampa Bay Buccaneers traded the fifth pick to the Jacksonville Jaguars, who selected Oklahoma State wide receiver Justin Blackmon. The Dallas Cowboys jumped to the sixth spot after a trade with St. Louis and took Louisiana State defensive back Morris Claiborne.
