Giants GM Dave Gettleman has shown a tendency to bring former Panthers players aboard from his time as GM in Carolina and two more have just hit the free-agent market.
Munnerlyn, who turns 31 in April, started in just five games over two seasons with the Panthers as their nickelback.
He finished the 2018 season with 47 tackles, nine pass deflections, an interception and two sacks.
The Giants do not have a lot of depth at cornerback and also have a decision to make with Janoris Jenkins, who they could cut and save $7.75 million toward the cap.
Cutting Jenkins, however, would force them to prioritize signing an outside corner, as opposed to someone who plays the slot like Munnerlyn.
Adams, meanwhile, turns 37 and is an unrestricted free agent after Gettleman signed him to a two-year deal in Carolina.
His age is certainly a factor that would make him a hard sell, but Gettleman certainly loves to bring in a veteran presence — see Jonathan Stewart — and Adams could definitely fill that role on a low-cost contract.
There is also a matter of how things play out between the Giants and Landon Collins.
Should the Pro Bowl safety fail to sign a franchise tag or long-term deal and enter free agency, the next man up would be 22-year-old Sean Chandler out of Temple.
Signing a veteran like Adams could give the Giants some insurance if things do not pan out with Collins and they feel Chandler is not quite ready.
