ALLEN PARK — Remember it is May.

During the Detroit Lions’ OTAs today (Wednesday), the defense was clearly ahead of the offense. That is not unusual this time of year.

The issue, though, was familiar — drops.

“Today was a little sloppy, I’m not going to lie to you. I was getting a little angry today, mostly the drops and some of the alignments were not what you want,’’ offensive coordinator Joe Lombardi said. “It was really a concentration issue more than anything. I’m pretty excited about these players we have and the way this thing is going to develop.’’

He understands this was an issue in the 2013 season for the Lions even though he was the New Orleans Saints quarterbacks coach.

Lombardi also can pinpoint a few reasons for so many drops in Wednesday’s practice and sees the situation improving.

“I think it’s always a concern, but I do think there’s good hands here so it’s really a matter of concentration and getting these guys the reps,’’ Lombardi said. “And a lot of it is getting their comfort level down, they’re still learning the offense and so they’re thinking where do I line up? What’s the depth of my route? When they get more comfortable their concentration will come up a little bit and they’ll catch the ball better because they do have good hands.’’

Wednesday was the fifth of 10 organized team activities allowed by the NFL collective bargaining agreement. The Lions will have one Thursday, four next week and then have a mandatory minicamp June 10-12.
