JACKSONVILLE, Fla. -- This is what an offense with a deep-threat tight end, an experienced receiver and a healthy array of complementary weapons can do for the Green Bay Packers.

And it sure looked a lot different than the group that scuffled through last season.

It’s not yet a well-oiled machine -- after all, it was the first time quarterback Aaron Rodgers and Jordy Nelson played a game together in nearly 13 months -- but in a 27-23 road win over the Jaguars, it was an acceptable start to a season chock-full of expectations.

In Sunday’s Florida heat -- at 90 degrees it tied for the third-hottest game in Packers history -- Green Bay’s offense was an improved version of the unit that ranked 23rd in the NFL last season.

Rodgers enjoyed the spoils that an offseason provided -- the addition of free-agent tight end Jared Cook (who drew a key pass interference penalty), a recovered Jordy Nelson and a deep receiver group with two rejuvenated players in Randall Cobb and Davante Adams.

Together, it provided an optimistic start to the season, even though it took about a quarter of football to get going. Nelson, in his first game since he tore the ACL in his right knee in the 2015 preseason, didn’t go deep, but he did enough (six catches, 32 yards and his first touchdown since Dec. 21, 2014).

The key to the whole thing against the Jaguars might have been something that won’t show up on the Packers’ offensive stat sheet. Cook, the lanky and speedy tight end who signed a one-year, $2.75 million deal with Green Bay after the Rams cut him, ran down the seam and drew a 30-yard pass interference penalty. It was the perfect start to a two-minute scoring drive that ended with perhaps one of the best plays of the NFL’s opening Sunday of 2016: Rodgers’ 29-yard touchdown pass to a diving Adams.

Not many quarterbacks have the arm strength to make that throw, particularly with Jags cornerback Jalen Ramsey grabbing the back of Rodgers' jersey.

But it wasn’t a flawless day. While trying to run out the clock late in the fourth quarter, Rodgers had to burn a timeout, and the Packers followed that with an inexcusable delay of game penalty that turned a third-and-short into a third-and-long and then a punt. Previously, an apparent miscommunication between Rodgers and the offensive line on third-and-goal from the 2 saw the line pass-blocking while Rodgers handed off to Starks, who got stuffed.

Still, it was an assortment of riches compared to what Rodgers had at the end of last season, when he was down to the likes of Jeff Janis and Jared Abbrederis in his receiving corps in the playoff loss at Arizona.

With Rodgers throwing for two touchdowns and running for another, he now has the kind of weapons that he needs.
