League sources on Wednesday told Matt Maiocco of Comcast SportsNet Bay Area that mutual interest exists between Asomugha and the 49ers. ProFootballTalk.com reported that three other teams -- the Houston Texans, Denver Broncos and Arizona Cardinals -- also have their eye on the 31-year-old defender.
Asomugha earned $21 million over two seasons with the Eagles, and Philadelphia wasn't about to pay another cent of the five-year, $60 million contract he signed in 2011. Whatever contract Asomugha lands next is certain to be modest by comparison.
The 49ers might get a bargain if they wind up landing Asomugha. He was underwhelming in Philly -- intercepting just four passes over 31 starts -- but we've seen Jim Harbaugh work wonders with veterans and players left for dead. With a burning need at cornerback, the 49ers could do worse.
