If Moss proves himself during workouts this spring and training camp, he could be a viable deep threat that San Francisco hoped it had in Braylon Edwards last season.
The 49ers cut ties with Edwards in December. Joshua Morgan broke a bone in his lower leg Oct. 9 against Tampa Bay and later had surgery to have screws inserted and was placed on season-ending injured reserve. Morgan is expected to generate his share of interest in free agency, and receiver and return man Ted Ginn Jr. might not return.
Michael Crabtree, San Francisco's 10th overall pick in the 2009 draft, had 72 receptions for 874 yards and four touchdowns in 2011. San Francisco went 13-3 and ended an eight-year drought without a playoff berth or winning record.
Moss' best season came for the Patriots in 2007, when he caught 98 passes for 1,493 yards and a single-season record 23 touchdowns in helping New England to a 16-0 regular-season record. He has 954 catches for 14,858 yards and 153 TDs in his 13-year career, which included a stint in the Bay Area with the Oakland Raiders in 2005 and '06 where he produced little on the field.
Running back Anthony Dixon watched Moss' workout Monday, and came away giddy.
"Randy Moss done linked up with us. Oh it's about to get scary like the end of October!" Dixon tweeted.
Moss has had more than 1,000 yards receiving in a season 10 times, second only to Hall of Famer Jerry Rice, who accomplished the feat 14 times.
Moss hasn't lost his swagger.
"I accept the challenge and I'm ready to bring the fans out of their seats," he said, noting he considers this a chance to give back to the game. "I like what I can do for the NFL. I don't like what the NFL can do for me."
ESPN first reported the move a day before the start of the free agency period.
