Camp will consist of a blend of classroom work, with rookies getting their first look at the playbook, basic orientation to an NFL player’s routine and on-field drills designed to give coaches a sense of how quickly the young players grasp and apply the concepts.

On Saturday, reporters will get their first look, interview players and hear from Coach Jay Gruden. Here are five story lines to follow in the coming days:

1. Is wide receiver Josh Doctson, McCloughan’s surprise first-round pick, ready to stake a claim for significant playing time in a crowded receiving corps? Doctson, a 6-foot-2, 202-pound wide receiver from Texas Christian, wasn’t the only person stunned when the Redskins chose him with the 22nd overall pick. McCloughan said he was stunned to find Doctson still on the board. So, true to his vow to choose what he deemed the “best player available,” he picked him, insisting later that Doctson’s addition would have no bearing on the status of incumbent starters DeSean Jackson and Pierre Garcon, who are entering the final year of their contracts.

But no NFL team spends a first-round pick on a player it doesn’t expect to start. The question is: How close is Doctson to claiming that role? His size alone solves one problem for the Redskins, giving quarterback Kirk Cousins another large target to complement 6-3 tight end Jordan Reed in red-zone situations.

2. How does defensive coordinator Joe Barry intend to use Su’a Cravens, the hybrid Southern California linebacker and defensive back that McCloughan believes can make splash plays at several spots on the field? Heading into rookie camp, the Redskins are listing Cravens as a safety. They surely need help there; the entire defensive backfield was ravaged by injury last season and in the offseason released high-priced veteran Dashon Goldson. Cravens, who’s regarded as a high-motor, high impact player, is expected to see plenty of action his rookie season — whether at safety, linebacker, nickel linebacker or nickel corner.

3. Don’t expect to hear much news of Virginia Tech cornerback Kendall Fuller, whose selection in the third round may represent McCloughan’s biggest gamble. Fuller is recovering from microfracture surgery on his right knee and isn’t ready to join teammates for on-field work. He’s also the only pick among the seven-member draft class who has yet to sign his contract. Nonetheless, McCloughan has seen enough video of Fuller — and has enough respect for his lineage and work ethic as the fourth Fuller brother to play for Virginia Tech before entering the NFL — to believe he has starting potential. Along with the blockbuster addition of 28-year-old Josh Norman following a career-best season with the Carolina Panthers, Fuller’s upside is partly why McCloughan felt comfortable releasing veteran cornerback Chris Culliver two days after the draft.

4. All four of the Redskins’ late-round picks are signed and expected to take the field: defensive tackle Matt Ioannidis, a fifth-round pick from Temple; Indiana’s strapping quarterback Nate Sudfeld; Boston College inside linebacker Steven Daniels and Georgia running back Keith Marshall.

So, too, are dozens of undrafted college players — some already under contract, others simply invited on a tryout basis. Among the undrafted signees are Arizona State cornerback Lloyd Carrington and Florida State linebacker Reggie Northrup. Among those who’ll take part on a tryout basis are James Madison center Dominick Richards, a former tight end who started all 12 games at center in 2015. Who among them will shine? This time last year, Louisiana Tech linebacker Houston Bates did just that, among five tryout players signed by the Redskins immediately after rookie camp. Bates appeared in 10 games last season.

5. With more rain and possible thunderstorms forecast, Gruden will tailor the schedule around the elements. At present, the Redskins have no indoor practice facility. Plans to replace the four-year-old indoor bubble that collapsed under January’s record snowfall are behind schedule. Delaying rookie camp until the new indoor facility is completed (June 1 is the new target date) wasn’t an option because the NFL permits just two windows for the rookie workouts: May 6-9 and May 13-16.

But the Redskins won’t risk any injuries on a slippery field, particularly after injuries crippled the defensive backfield last season. Partly because of injury concerns, the Miami Dolphins aren’t holding any on-field workouts as part of their rookie minicamp this summer. First-year head coach Adam Gase has said he feels the time is better spent in the classroom, honing the mental game. And, like every NFL coach, he surely recalls that Jacksonville lost Dante Fowler Jr., the No. 3 overall pick in the 2015 draft, to an anterior cruciate ligament injury on the opening day of rookie minicamp last May.
