Welcome to the purest week of the NFL calendar.

Free-agent signings and draft picks come together with veteran holdovers — even most of the ones who skipped voluntary OTAs due to a contract dispute or some other obligation — to form the rosters that general managers and coaches envisioned assembling in their minds during the offseason.

There are 22 teams holding mandatory minicamps this week. Players who no-show for physicals or the two practices (totaling 3 ½ hours on the field per day) are subject to fines.

You still won’t see pads or live contact in 11-on-11 drills in minicamp, which means optimism will run high for the possibilities ahead. It’s like the “turn injuries off” function in the Madden video game.
