The NFL draft is where you can hit a home run with a pick like Tom Brady, or where you can blow a pick like Ryan Leaf.
However, the draft is also where you can make trades to build your team for the future. With the Donovan McNabb trade completed and the draft a few weeks away, let's look at some of the biggest draft-day trades in NFL history.
These are the trades that happened during the draft, not picks or players that were traded before.
"The Bus" made his way to Pittsburgh after a change in coach and philosophy in St. Louis.
The Steelers traded a second round pick in ’96 and a fourth-rounder in ’97 for Bettis and a third-round pick. He would go on to win a Super Bowl with the Steelers in his final season with the team.
After playing his way out of Oakland, Randy Moss was acquired by the Patriots for a fourth-round selection in the 2007 draft. Moss quickly returned to his old form and set the record for most receiving touchdowns in a season, with 23.
The Dolphins acquired the still-great Warfield from the Browns in a controversial trade orchestrated by Browns owner Art Modell.
The Browns sent the speedy receiver to the Dolphins for a first-round pick in the 1970 draft. The Browns went on to use the pick to select Purdue All-American quarterback Michael Phipps.
In 1990 the Colts thought they had found their quarterback of the future when they completed a trade with Atlanta that would allow them to draft hometown QB Jeff George.
To acquire his services, the Colts traded their fifth-round pick in ’90, their first-round pick in ’91, wide receiver Andre Rison, and offensive tackle Chris Hinton.
The Falcons were desperate for a quarterback in 2001, and all-world athlete and quarterback Michael Vick was the top prize in that year's draft.
The Falcons made a trade with the Chargers, who held the No. 1 pick. Atlanta traded their first-round pick, third-round pick, their second-round pick in 2002, and wide receiver Tim Dwight to acquire the No. 1 pick.
After stating he would not play for the Chargers, Eli Manning was still drafted No. 1. However, he was soon dealt to the Giants for No. 4 pick Philip Rivers.
The Chargers, in addition to Rivers, got the Giants' third-round pick that year and their first- and fifth-rounders in the 2005 draft. The Chargers used the picks on Nate Kaeding and Shawne Merriman. They also traded the fifth-rounder to Tampa Bay for offensive lineman Roman Oben.
The Cowboys made off like bandits in 1977 when they completed a four-for-one deal with the Seahawks. The Seahawks traded their first-round pick (No. 2 overall) to the 'Boys for the No. 14 overall pick and three second-round picks. The Cowboys then rode Dorsett all the way to a Super Bowl title.
Mike Ditka traded eight (yes, eight) picks for the right to select Texas star Ricky Williams. In a deal that many people are still trying to figure out, Ditka sent six picks to the Washington Redskins in 1999.
He sent first-, third-, fourth-, fifth-, sixth-, and seventh-round picks, and then added a first- and a third-round pick in the 2000 draft. The 2000 first-rounder ended up being No. 2 overall selection. As you all know, this marriage didn't work out as planned.
A misunderstanding between Marshall Faulk and the Colts signaled his departure during the 1999 draft.
The Colts sent Faulk to the Rams in exchange for a second- and fifth-round pick. The Colts replaced Faulk by drafting Miami standout Edgerrin James with their first-rounder.
The 49ers acquired Steve Young, NFL greatness-in-the-making and the replacement for Joe Montana, from the Tampa Bay Buccaneers during the 1987 draft.
Young had become expendable in Tampa Bay after the Bucs signed Vinny Testaverde. The 49ers sent a second- and a fourth-round pick to Tampa Bay for Young.
The Patriots were in a position to grab the game's greatest receiver but passed when the 49ers offered multiple picks for their first-rounder.
The Patriots made the deal, sending their first-round and third-round picks to the 49ers for first-, second-, and third-round picks. The rest is history.
The Patriots redeemed themselves by acquiring Randy Moss in 2004, but that doesn’t make up for passing on Rice.
