GREEN BAY http://www.49erslockerroom.com/authentic-roger-craig-jersey , Wis. (AP) —Geronimo Allison against the San Francisco 49ers because of hamstring injuries.It’s the second straight week that the Packers will be without Cobb and Allison. Quarterback Aaron Rodgers will have to rely again on rookies Marquez Valdes-Scantling and Equanimeous St. Brown behind top wideout Davante Adams.Rookie cornerback Jaire Alexander will also miss the game with a groin injury. Starting right tackle Bryan Bulaga is active, though, after being limited the past two days of practice because of a knee injury.Green Bay’s other inactives are quarterback Tim Boyle, cornerback Bashaud Breeland, and offensive linemen Alex Light and Jason Spriggs.For the 49ers, leading rusher Matt Breida is active after coming into the game as questionable with shoulder and ankle injuries. Breida is sixth in the league in rushing with 369 yards.Receiver Pierre Garcon (shouder, knee) and tight end George Kittle (knee) are also active.Receiver Trent Taylor is inactive. He didn’t practice all week because of a back injury.The other inactives for San Francisco are: receiver Dante Pettis; tight end Cole Wick; offensive linemen guard Joshua Garnett and Shon Coleman; and defensive linemen Jullian Taylor and D.J. Jones. It’s easy to get excited about the potential of his second season in the NFL"Dante Pettis needs to stay healthy. If he is on the field for 16 games, the San Francisco 49ers have a weapon that few teams have. I still stand by him showing #1 traits as a rookie. That doesn’t mean Pettis is the next Jerry Rice. He confirmed everything you look for in a wide receiver.Statistically, Pettis is in great company. Mick Smiley of Cat Scratch Reader had an excellent idea for D.J. Moore, and I wanted to see how Pettis stacked up. Smiley coined the term “P.I.P.E,” which stands for potential, impact Garry Gilliam Jersey White , production, and efficiency.Potential - Drafted in the first or second roundImpact - Averaged at least 14 yards per reception as a rookieProduction - Registered at least 700 receiving yards as a rookieEfficiency - Averaged at least nine yards per target as a rookieI’m fudging the production number here for Pettis. He had 467 yards on 45 targets. Everyone else you’ll see on this list had at least 74 targets. With 30 more targets, I’m going out on a limb and saying Pettis would have eclipsed 700 yards.Pettis was selected in the second round. Whether we want to admit it or not, there’s more pressure on players that are drafted early to produce. So I think it’s crucial that these criteria are there. Before we get into the rest of Pettis’ numbers, here are the players who qualified for “P.I.P.E” over the last 15 years. Pettis averaged 17.3 yards per reception as a rookie. That would put him third on this list.The final piece would be efficiency. Pettis averaged 10.4 yards per target, which would put him fourth on the list. While Moore is squeaking by the filters Smiley made, Pettis is passing with flying colors.While it helps that Pettis will be in a receiver friendly system, he does plenty of heavy lifting himself. Of his 27 receptions, 14 of those went for over 10 yards, and 19 of those catches resulted in first downs. Pettis is efficiency. The long touchdown didn’t inflate his numbers against the Seattle Seahawks. There is a lot of consistency to Pettis. That’s why it’s easy to get excited about what his sophomore year will look like.
