OK, the NFL is back. The players approved the new CBA this afternoon. Facilities open Tuesday for voluntary conditioning and classroom work. The Lions open camp on Thursday.

Here are my three immediate questions:

1. What will be the Lions’ approach to free agency? Obviously the two big needs are at cornerback and linebacker. If they can’t strike a free agent deal, expect Martin Mayhew to improve the roster via trades. Last offseason he made a number of trades to bring in key players like Corey Williams, Shaun Hill, Lawrence Jackson and others.

2. Will all players report in good shape? Many of them have tweeted about their workouts and now we’ll find out who was serious about the workouts and who wasn’t. The 30 or so players who showed up at the team’s informal workouts at Detroit Country Day in May and June appeared to be in good shape, but what about the rest?

3. How will training camp differ from camps in non-lockout years? First of all, it’s in the agreement that they can’t hit at camp for the first three days. I don’t think it’s going to be all that different. Coach Jim Schwartz gradually gets them in pads anyway. Schwartz and his staff have had plenty of time to plan for this camp. Of course, so have the other 31 NFL coaches.

OK, that’s just for starters ...
