Like 28 other NFL teams, the Detroit Lions will have OTAs (organized team activities) this week. The first session is on Tuesday.

No contact, no one-on-one drills and also no blocking, tackling, pass-rushing and bump-and-run situations. That’s all in the Collective Bargaining Agreement.

They will be allowed 11-on-11 drills which will give us an initial idea of where some players might line up.

 It’s not like training camp where the competition will be hot at a handful of positions. It is a start, though.

Here are five things to look for at OTAs:

1. Will be interesting to see top draft pick Ziggy Ansah line up against veterans. Expect to see him at right defensive end. He looked really quick off the end in rookie minicamp. Let’s see if that sticks against Riley Reiff.

2. Even  though one-on-one drills matching defensive backs against wide receivers aren’t allowed, will get our first look at safety Glover Quin who signed as a free agent and should play opposite Louis Delmas. Not sure if we’ll see second-round pick cornerback Darius Slay. He had minor knee surgery a few weeks ago. He’ll be back sooner rather than later, but this might be a little too soon.

3. Of course, it’s early but we’ll get a look at whether Corey Hilliard or Jason Fox lines up at right tackle with the starters. It does not mean that guy will be the right tackle in September, but it’s a starting point.

4. Also will get a first look at the competition at wide receiver. Other than Calvin Johnson, Nate Burleson and Ryan Broyles (when he gets healthy) there are no absolutes to make the team. Should be great competition.

5. Reggie Bush in a Lions’ uniform. No doubt he seems excited to get going. Expect it will seem a little different seeing him in Honolulu blue and silver even though we’ve had two months to get used to the idea.
