I wonder if OLB Adalius Thomas is someone they'd be interested in. I suspect he's on the trading block since he was a healthy scratch on Sunday after starting the first 5 games this year.
He's getting towards the end of his career -- 10th year -- but he's probably good for 5 or 6 sacks this year.
He'd be good OLB depth for the Niners along with Ahmad Brooks.
The Niners were supposedly the other team very hot for Thomas when he hit FA, to the point where a lot of media were suprised he signed with NE instead of SF. Plus, he's a known quantity for Singletary from their time together in Baltimore.
If NE lets him go for a 4th round pick or a couple of lower picks, I'd be in favor.
