Put them side by side and Greg Jennings knows who he is going with.

The Green Bay Packers wide receiver has played with Brett Favre and Aaron Rodgers, who have each led the franchise to a Super Bowl championship. Jennings, who played with Favre for two seasons and now Rodgers for the last four, believes he knows which quarterback is better.

"They both bring different things to the table, but, honestly, right now, I definitely have to go with -- you can't take away what Brett has done -- but I am gonna go with Aaron," Jennings said on ESPN radio, according to NFL.com.

"His body of work at such a young age, his attention to detail, his discipline, I think it's really second to none and I think it's unparalleled," he said. "And you haven't really found a quarterback that has done it the way he's done it. You have the young guys that are coming out and they're making a huge impact in this game.
 

"This is a different league, it's a pass-first league and so it's a little different, but his attention to detail and his discipline to be perfect or so close to perfect -- I think that's really going to separate him ... I am definitely going to have to go with 'A-Rod.' "
 

Jennings has been out with a sprained knee but is expected to return Sunday when the Packers host the New York Giants in the divisional round. He missed the final three regular-season games.
