But if you ask Packers receiver Greg Jennings, Rodgers doesn't need the second title to validate his place in Lambeau lore.
"They both bring different things to the table, but honestly right now I definitely have to go with ... Aaron, his body of work at such a young age, his attention to detail, his discipline, I think it's really second to none -- its un-paralleled," Jennings said on "The Ian O'Connor Show" on ESPN New York 1050 on Sunday when asked which player he thought was the better quarterback.
Jennings played his first two years in the league with Favre under center for Green Bay, but his numbers have exploded since Rodgers took over to start the 2008 season.
The Western Michigan product has caught 291 passes for 4,619 yards and 34 touchdowns in 61 games with Rodgers, as opposed to 98 receptions, 1,552 yards and 15 touchdowns in two seasons with Favre.
"You haven't really found a QB that has done it the way (Rodgers) has done it," Jennings told ESPN 1050. "I mean you have the young guys that are coming out and they're making a huge impact in this game ... but his attention to detail and his discipline to be perfect or so close to perfect I think that's really going to separate himself ... his study habits are ... they speak volume for themselves."
Jennings tore his left medial collateral ligament in the Packers' Dec. 11 victory over Oakland, and sat out the final three games of the regular season. He is expected to be ready to go when top-seeded Green Bay (15-1) hosts the New York Giants in the divisional round next weekend.
