When the premier pass-catcher in NFL history can be traded, as was the case with Jerry Rice (from Oakland to Seattle) in 2004, anything -- or more appropriately, make that just about anybody -- goes.
And when it comes to the wide receiver position, that "anything goes" approach has pretty much been the philosophy under which the league has operated in recent years.
Thirty-one veteran wide receivers have been dealt since the spring of 2006, according to the "NFL Record & Fact Book" -- including this week's trades of former Super Bowl MVP Santonio Holmes and two-time Pro Bowler Brandon Marshall.
And there figure to be more before next weekend's draft, during the draft, and after it.
"[That's] a lot of action at receiver," said three-time Pro Bowl wide receiver Anquan Boldin, traded from Arizona to Baltimore this spring. "It's like wide receiver has kind of become the currency of choice in the league these days."
There have been a few wide receiver deals that were good investments and more that were the equivalent of counterfeit $100 bills. Among the former were trades involving Randy Moss and Wes Welker, both to New England in 2007. The latter? Take your pick: Roy Williams (to Dallas, 2008), Mike Williams (to Oakland, 2007), Darrell Jackson (to San Francisco, 2007), Javon Walker (to Denver, 2006), Deion Branch (to Seattle, 2006) and plenty more.
But the lopsided bust-to-boom ratio certainly hasn't stopped franchises from making deals to acquire veterans as the pass-catcher spot becomes increasingly devalued by the diva nature of the position, declining skills, age, disappointing production, internecine squabbling and various off-field indiscretions.
Those factors, or a combination thereof, certainly have created a buyer's market this offseason.
Of the four veteran wide receivers traded through Thursday evening, three (Boldin, Marshall and Holmes) had combined for six Pro Bowl appearances, two Super Bowl berths, a Super Bowl title and a Super Bowl MVP award. But Marshall and Boldin either wanted their contracts reworked or squabbled with management (or both), and Holmes faces a four-game suspension (the second disciplining) of his career.
The fourth, Reggie Brown (Philadelphia to Tampa Bay), was a second-round pick in 2005 but only once caught more than 60 passes in a season, just once posted more than 800 yards, and had dropped precipitously on the Eagles' depth chart as the club revamped the position with exciting youngsters DeSean Jackson and Jeremy Maclin.
Notably, none of the four wide receivers traded to this point included a first-round draft pick in return. Brown was shipped to the Bucs for a sixth-rounder. Despite his first-round pedigree and MVP award in Super Bowl XLIII, Holmes netted the Steelers only a fifth-round pick from the Jets. The Steelers, who reportedly were prepared to release Holmes outright, were fortunate to net that much in return in the giveaway fire sale.
The Jets have taken advantage of the deflated market to add two starters (Braylon Edwards and Holmes) in the past seven months. Total compensation: three middle-round draft choices (a third-rounder and two fifth-round picks) and a trio of backup-caliber veterans. Of course, New York must now find a way to handle its talented but troubled windfall, but general manager Mike Tannenbaum suggested coach Rex Ryan possesses "a unique skill set" that permits him to deal with such flawed players.
In the meantime, expect the Filene's Basement-type bargain discounts to continue. Not since the Williams deal in '08 has a wide receiver trade included a first-round draft pick. Before that, it was the Branch swap in 2006.
Sports psychologist Larry Kessler has cited the "diva quotient" at wide receiver as critical in driving down trade prices. Although attempts to reach him this week were unsuccessful, sports consultant Jonathan Niednagel acknowledged a few years ago that wide receivers might be "wired differently" than players at most positions.
And there is this fact, as well: Over the past five seasons, there have been 26 different wide receivers who registered at least 70 catches and eight or more touchdowns in the same season. Ten of those players originally entered the NFL in the third round or after, with seven in the sixth round or later.
Three of those players originally came into the league as undrafted college free agents.
"You can find somebody late, who, if he's got talent and works hard, can catch the ball," said New Orleans wide receiver Marques Colston, a three-time Pro Bowl performer and a seventh-round pick in 2006.
That certainly seems to be the case in the 2010 draft, regarded as one of the deepest talent pools in recent years.
