GREEN BAY, Wis. -- It's still football in shorts and helmets -- "I've graduated from saying underwear. My mother didn't like it when I said that before," Green Bay Packers coach Mike McCarthy said recently -- but the next phase of the offseason program at least bears a resemblance to what we'll see this summer in training camp.

The Packers, and the rest of the NFL, begin Phase 3 of the offseason this week, which most teams call organized team activities.

Some teams get under way on Monday. McCarthy will begin his program on Tuesday.

The rules of the collective bargaining agreement that went into NFL law in 2011 spell out the OTAs this way:

Number of OTA days allowed : 10

Hours of work allowed per day at team facilities : 6 (an increase of two hours per day over Phases 1 and 2)

Acceptable drills allowed: 7-on-7, 9-on-7 and 11-on-11 drills are permitted for the first time in the offseason, but no live contact or 1-on-1 between offensive/defensive linemen or receivers/defensive backs.

Here’s the Packers' schedule for the remainder of the offseason:
