The veteran cornerback, who has been battling knee and groin injuries, said he feels better than he did a week ago and is preparing to play Sunday when the Bears host the Saints.
"He's so damn accurate," Tillman said. "That's the biggest challenge that we have. The way you take that away is pass rush. I think this will be a good game for our d-line to get some pressure on Drew and hopefully he can throw us some [passes to intercept]."
Brees no doubt will look to tight end Jimmy Graham, an athletic 6-7, 265-pounder who is tied for the NFL lead with six TD receptions and ranks second among all pass catches with 458 yards.
"He's a tough match-up, but we have guys too," Tillman said. "It's not just about what Jimmy Graham can do or what Drew Brees can do. Don't get me wrong; I think they're great players and they're at the top of their game. But we have good guys on our team as well."
With Paea hurting and
Regardless of who plays, the Bears defensive tackles must perform better than they did in last Sunday's 40-32 loss to the Lions in Detroit.
"The guys have worked really hard and it's the next-man situation," said coach Marc Trestman. "We expect to go out there and play well inside. Guys are down. It happens all over the league. We're dealing with it this week just as other teams are throughout the league."
Five Saints players have been ruled out of the game with injuries: Defensive ends Brodrick Bunkley (calf) and Tyrunn Walker (knee), running back Mark Ingram (toe), safety Roman Harper (knee) and receiver Lance Moore (hand).
