I've got no rooting interest in any 4 teams.
That said, after seeing Rodgers dismantle the Falcons, I'd definitely take the Pack and give the points (you know, if gambling was legal). That guy made some incredible throws. Haven't watched many Pack games, but he's got a cannon of an arm and he can move and throw. Bears are good and they're home, but I don't trust Cutler in a big game.
I like Big Ben over Sanchez in the AFC. Sanchez looked terrible in the Colts game and their D just beat down the Pat's offense by clogging the middle and jamming the recievers at the line. Brady looked lost and the recievers just weren't able to get open for those quick passes that made NE so great in the regular season. Ben just wins though. And if the Jets shut down the Steeler WR, I think their running game can take over.
Both are going to be great games! Bears/Pack is great rivalry football and Jets/Steelers should make for some hardnose defensive struggles. Both teams are very outspoken and should carry over onto the field Sunday. Brewing a Vienna lager Friday night and a co-op 10 gallon batch of BW and a 5 gallon second runnings beer on Saturday so I should have my entire Sunday free for 8 hours of football.
