The Green Bay Packers (3-2) will end their mini bye week with a trip south to sunny Miami, where the Dolphins (2-2)—fresh off a full bye week—and the heat of south Florida await for a non-conference clash in Week 6. 

Here's five things to watch and a prediction:

1. Speed on Speed

Two of the fastest players at their respective positions—Dolphins receiver Mike Wallace and Packers cornerback Sam Shields—will go head-to-head Sunday. The long-striding Wallace has hurt Green Bay in the past, catching two touchdowns back in a 2009 meeting and another score in Super Bowl XLV. He has 32 career catches over 40 yards, although only five have come during his 20 games in Miami.

Shields has given up some big plays, including four catches over 20 yards, but he's generally been solid playing on the perimeter this season. He simply can't get caught peeking—arguably his biggest weakness as a cover man—against a speedster like Wallace. One bite and the Dolphins are capable of scoring six. Makeup speed doesn't matter much when dealing with Wallace. 

2. Test for the Tackle Duo

The Packers enter Week 6 ranked seventh in overall pass-blocking efficiency at Pro Football Focus, which might come as a surprise to some. Maybe it shouldn't. Only two tackle combinations have allowed less pressures this season than Green Bay's duo of David Bakhtiari and Bryan Bulaga (nine total), while guard Josh Sitton has given up just a single pressure (tied for first among guards). 

The two tackles will have their hands full in Miami, where Cameron Wake (two sacks, 19 pressures) and Olivier Vernon (two sacks, 13 pressures) will be called upon to disrupt the Packers passing game. Wake has a strong argument as the best 4-3 defensive end of the last four or five years, while Vernon broke out with 11.5 sacks last season. The Dolphins are perfectly capable of causing havoc with just four rushers if both Wake and Vernon are on. Bakhtiari and Bulaga need to hold their own and force Miami to bring extra people on the blitz, which is almost always advantage Aaron Rodgers. 

3. Tanny's Breaking Point

Like many teams, the Dolphins are difficult to beat when their quarterback plays well, and easy to defeat when the position plays poorly. However, the splits in Miami are even more defined with Ryan Tannehill under center. The Dolphins are 13-0 when Tannehill has a passer rating of 91.0 or over, and just 4-19 when he doesn't. When Tannehill's passer rating sinks below 79.4, or his career average, the Dolphins are 1-15, with the one win coming when Tannehill was knocked out of the game after five attempts. 

That's good news for the Packers, who are allowing an opposing passer rating of just 70.5 this season. Only the Bengals have been better. Green Bay has forced turnovers through pressure (on pace for 70 more quarterback disruptions in 2014), while also allowing only five touchdown passes. The Dolphins probably can't pull off the upset without Tannehill playing well Sunday.

4. Challenged Running

The Packers made clear progress in both running the football and stopping the run last Thursday against the Vikings. Green Bay rushed for season-high 156 yards (76 more than the offense's next best output) and held the Vikings to a season-low 111 rushing yards. Miami represents a more significant challenge for both sides. On offense, the Packers will face what Pro Football Focus considers the NFL's eighth best run defense. Of Miami's 11 preferred defensive starters, nine have a positive grade against the run through four games. The run defense is anchored by disruptive tackles Jared Crick and Earl Mitchell, while Jelani Jenkins has the third most run stops of any 4-3 outside linebacker. 

Offensively, the Dolphins use a Chip Kelly-like spread attack with zone-read principles, and are averaging 5.0 yards per carry. Both the darting Lamar Miller and powerful Knowshon Moreno, the offense's two main backs, have averages at or over 5.5 yards. For the Packers, stopping the run will become more difficult if Datone Jones (ankle) can't go. Expect the Dolphins to pound the football, especially against a young front in the hot Miami sun. The Packers can't get gashed on the ground and still expect to win Sunday. Ask the Patriots why. 

5. Rodgers in the Florida Sun

A week ago, Aaron Rodgers took down Mike Zimmer, one of his last remaining football adversaries. Rodgers can deal with another old enemy Sunday: the state of Florida. His three career starts in the Sunshine State have been mostly forgettable. 

The Packers lost all three games (one to Jacksonville, two to Tampa Bay), in large part because Rodgers threw seven total interceptions and had a combined passer rating of 65.4. Amazingly, over 13 percent of Rodgers' 53 career picks have come during just three games in Florida. There's no real rhyme or reason for why this is, save for the fact that all three games came in either 2008 or 2009, Rodgers' first two seasons as the starting quarterback. This is a different Rodgers, and a different Packers team. A quarterback always looking for even a tiny edge can check off another box Sunday in Miami. 

Prediction: Packers 28, Dolphins 20 (3-2)

The Dolphins' defensive line and ability to run the football on offense give Miami a fighting chance to pull off the upset. The heat should also be advantage Dolphins. That said, it feels like things are starting to click for the Packers. Tannehill won't play well enough to keep up.
