David Akers knows all about the ebbs and flows of an NFL season. This is the Lions kicker’s 16th season and although the field-goal unit isn’t off to a perfect start he’s confident the group will rebound. “There’s going to be a roller coaster ride” he said. “And it’s not throwing the baby out with the bathwater and it’s not saying you’re the greatest thing since sliced bread.” On Akers’ first field-goal try in Week 1 punter Sam Martin mishandled the snap and the Lions failed to score. Last week Akers had two chances at a field goal because of a running-into-the-kicker penalty. First he missed wide left from 52 yards and after the penalty he missed a 47-yarder wide right. Trainers had to stretch Akers out after he took the hit because he felt a pop in his hip but he said he’s healthy for Sunday’s game against the Redskins. Akers also had a kick blocked in the fourth quarter when Cardinals cornerback Justin Bethel ran untouched to the backfield. “It’s part of the game. You get blocks” Akers said. “You try to do your part and make the kicks when you can. It’s a team game any way you look at it and I can’t do my job unless 20 feet in front of me they’re doing their’s as well. Most of the time those guys are doing a great job. I can do a better job of getting it off faster.
