Long is the list of reasons why the 49ers would be crazy to trade for cornerback Darelle Revis, beginning with his lame-duck contract status and the fact he's coming off knee surgery.
As the late Raiders owner Al Davis learned with his puzzling signing of free agent wide receiver Javon Walker in 2008, bringing in a player coming off a knee injury not only is risky but can be downright foolish.
And yet if the 49ers are internally discussing Revis, as reported by trusted longtime acquaintance Jason Cole of Yahoo! Sports, they should continue contemplating.
With their pockets stuffed with as many as 15 picks in the 2013 NFL Draft, the Niners can afford to get crazy.
With a roster so deep they reached the Super Bowl while essentially "redshirting" their 2012 draft class, the 49ers are in position to be . . . a little foolish.
If there is a time to take a risk, it is now. If there is a guy worth the risk, it is Revis.
Prior to injuring his left knee early last season, Revis was unquestionably the best cover corner in the NFL. There is a reason they consider his portion of the field "Revis Island." He strands receivers, separating them from the rest of their friends on offense -- most notably the quarterback.
He's the one NFL player who can make a grown man vanish for three hours in front of 70,000 witnesses.
The 49ers have a great defense. It is the strength of the team. The weakest part of that defense is, yes, the secondary. It was exploited by Baltimore wide receiver Anquan Boldin in the Super Bowl. Two weeks before that in the NFC Championship Game, it was pantsed by Atlanta wideouts Julio Jones and Roddy White.
While San Francisco has one good cornerback, Carlos Rogers, surrounded by a couple young corners with potential, Tarell Brown and Chris Culliver, they don't have a cover guy around whom teams must game plan for.
They had such a guy on their last Super Bowl championship team. His name was Deion Sanders. He was the best cover corner of his era.
Revis doesn't have Deion's full athletic arsenal; he brings no electrifying kick returns. But Revis' ability to cover, prior to the injury, was equal to that of Sanders
So, yes, evaluate him. And if his knee passes inspection and the Jets are willing to listen, the 49ers should get to work on a deal -- even if there are no assurances Revis would extend his contract beyond the one year remaining.
If they can't make a bold move while holding more draft picks than they could possibly use, when can they?
