It has been about six weeks since free agency began and in true form … nobody’s heard a word about Marvin Harrison. After being released by the Colts on Feb. 24, there hasn’t been a single report of Harrison visiting potential suitors.

Marvin Harrison has garnered no interest in the free agent market.

Marvin Harrison has garnered no interest in the free agent market.

Coming off the first major injury of his career, Harrison — now 36 — obviously lost a step in 2008. But he stayed fairly healthy and showed occasional flashes of his old self.

Wide receivers were at a premium in free agency this offseason and plenty of teams are still in desperate need of one — Chicago, Philadelphia, and the NY Giants to name a few. It’s odd that nobody’s taken a serious look at Harrison, who had 60 catches for 636 yards and 5 TDs last season and is still a precise route-runner.

Joey Galloway recently signed with the Patriots —he’s 37 and only caught 13 balls last season.

Bobby Engram found a home with the Chiefs — he’s 36 and had one of his least productive seasons in some time last year.

Torry Holt has been a free agent for less than a month and has already visited the Titans and Jaguars — he turns 33 this summer and had similar numbers to Harrison’s last season (64 catches, 796 yards, 3 TDs).

There are two likely scenarios that may explain why Harrison is garnering zero interest around the NFL — either he doesn’t want to play anymore, or his market value is far below what he thinks he’s worth.

I’m guessing the latter.

Nobody knows much about Harrison, but it’s clear he has a lot of pride. He currently ranks second all-time in receptions (1,102); fourth all-time in receiving yards (14,580); and fifth all-time in touchdown catches (128). Harrison’s a relentless worker and a Hall of Fame shoe-in when he calls it quits.

His agent Tom Condon has surely put out feelers and may be coming back with information Harrison doesn’t want to hear.

At this point of his career, Harrison is a No. 2 receiver at best. He was scheduled to make about $13 million with the Colts in 2009 and would likely have to settle for a mere fraction of that with another team.

For elite athletes it’s often hard to accept when the end is near.

Harrison may think he’s still an elite receiver, while it has become obvious that he’s not. The future won’t hold any more All-Pro nods or Pro Bowl appearances for Harrison, but he will get another shot.

Whether or not he takes it is up to him. One thing is for sure — nobody but Harrison knows what he’s thinking. Some things never change.
