Take away Wynn's home run, and Green Bay gained but 47 yards in 26 rushing attempts -- not including two kneel-downs by Brett Favre to end the game.
The Packers rushed for only 46 yards in their season-opening win over the Eagles.
Head coach Mike McCarthy wasn't quick to write off the contributions of Wynn, who had two TD runs and finished with 50 yards in 10 carries.
"DeShawn's run counts," McCarthy asserted Monday of the big gain. "They all count on both sides of the ball. Those two runs do count."
McCarthy, though, lamented another dose of poor execution by the offensive line. This time, the Giants periodically blew up running plays with their penetration.
"The negative of our run-blocking unit was (New York's) free hitters; we had three or four free hitters," McCarthy said. "I don't care what kind of scheme you have, there's no design for a defensive lineman to run free to the backfield.
"We had some mental errors that are very uncharacteristic of that group (the offensive line). That's a group that has a lot of pride, and they spend a lot of extra time together. We'll get that fixed; I can promise you that."
The Packers still are waiting on halfback Vernand Morency to play in a game. Morency has been dogged of late by soreness that flares up in his right knee after he practices. The projected starter sustained a strained patellar tendon in the knee on the first day of training camp and won't be cleared for game action until he's pain-free.
Morency will be questionable for Sunday's game against the Chargers.
Returner sparks rejuvenated special teams
Former practice-squad player Tramon Williams has been at the heart of a resurgence by Green Bay's special teams, which statistically ranked last in the league each of the previous two seasons.
Williams is the NFC's No. 2-rated kickoff returner with a 28.0-yard average, buoyed by a 42-yard runback to start the second half Sunday. It led to a touchdown that put the Packers ahead to stay 14-10 en route to the lopsided win.
Williams, a cornerback, is a speed demon and has sufficiently filled an early-season void created by a broken thumb suffered by top returner Will Blackmon. The coaches are keeping Blackmon off returns -- punt and kickoff -- until he proves to them that he can consistently catch the football with a small cast on his left hand.
Williams averaged 34 yards in two kickoff returns Sunday. A 46-yard runback late in the first half was nullified by a holding penalty on Colin Cole.
"Tramon Williams is going to be the kickoff guy until something else happens," special teams coordinator Mike Stock said after the game. "Right now, this guy is the guy. He's improved every week."
Williams' big return that counted in the second half preceded the latest in a string of impact plays already made by the coverage units.
Former Giant Charlie Peprah caused a fumble on Ahmad Bradshaw's kickoff return early in the fourth quarter. Tracy White made the recovery deep in New York territory, and the Packers cashed in with their second touchdown in less than two minutes to blow the game open at 28-13. White had a fumble recovery for a touchdown on a muffed punt return by the Eagles in Week 1.
The Packers' special teams have forced three turnovers in the first two weeks. They didn't have any last season.
Top emergency quarterback candidate
WR Ruvell Martin is a candidate to be the emergency No. 3 quarterback. Fellow receiver Carlyle Holiday was being groomed for that role but was placed on injured reserve Saturday with a knee injury.
