"Dallas Cowboys quarterback Tony Romo and his Sunday counterpart, the Green Bay Packers' Aaron Rodgers, are virtually identical, on paper.

Both stand 6-foot-2. Romo weighs 226 pounds; Rodgers is 220. Each has a strong right arm and legs that serve them well.

Their season statistics are strikingly similar.

A Wisconsin native, Romo has a free-wheeling style often compared to Packers legend Brett Favre, while Rodgers has the more unenviable task of having to replace Favre.

Even their golf games are close.

Yet, on the field they seem so different.

Rodgers, who will be 26 on Dec. 2, appears taller and brawnier in the pocket. Romo, 29, seems more athletic, a superior scrambler, swashbuckling even compared to Rodgers' more measured, yet highly effective, maneuvering. Romo celebrates touchdowns with wild leaps into the arms of his linemen. More composed, Rodgers barely cracks a smile.

"They look different," said former Cowboys personnel director Gil Brandt, "but they're really the same."

As two of the NFL's best young quarterbacks converge Sunday at Lambeau Field with their teams headed in opposite directions — the surging Cowboys (6-2) have won four in a row; the desperate Packers (4-4) have dropped two in a row — the most glaring difference between the two might be the heavies who protect them.

Rodgers, the NFL's top passer until Sunday's three-interception game at Tampa Bay dropped him behind Drew Brees, Favre and Peyton Manning, has been sacked a league-leading 37 times.

Some of those are on Rodgers, who'll hold on to the football, trusting his receivers will break free. The Packers are tied atop the league with the Cowboys and Eagles with 10 pass plays of 40 yards or more.

Holding on too long, however, is a double-edged sword. Rodgers is on pace to surpass David Carr as the most sacked in a single NFL season."
