The correlation between attendance at organized team activities and regular-season success is unclear. Some of the Ravens' top all-time players — Ray Lewis, Ed Reed, Haloti Ngata and Terrell Suggs — preferred to skip the workouts and not put themselves at additional risk of injury.
Other teams crow about having perfect OTA attendance, and how much the "voluntary" sessions mean in the team-building process.
For the Ravens, any time on the field before training camp is valued. Over the next three weeks, rookies and veterans will participate in the OTA phase of the offseason. Starting Tuesday and ending the week of June 5, Ravens players will be on the field for a total of 10 workouts.
That number could be reduced if the league imposes discipline for the Ravens violating the collective bargaining agreement by having players in full pads at the rookie minicamp this month. Players are not permitted to wear full pads in the OTAs and live contact is also not allowed.
With training camp still two months away, here are some of the OTA storylines to watch:
1.) Who won't be there?: Because of the number of players coming back from significant surgeries and injuries, the Ravens team that will be on the field Tuesday stands to look significantly different than the one that will play the Buffalo Bills in the regular-season opener on Sept.11.
Quarterback Joe Flacco (knee), wide receiver Steve Smith Sr. (Achilles), Suggs (Achilles) and cornerback Jimmy Smith (foot) all are doubtful to participate in any of the OTAs. Running back Justin Forsett (arm), tight end Crockett Gillmore (shoulder) and center Jeremy Zuttah (pectoral) are still working their way back and could be limited as well.
Right guard Marshal Yanda and strong-side linebacker Elvis Dumervil traditionally don't show up until the mandatory minicamp. It also wouldn't be surprising for kicker Justin Tucker to stay away from voluntary team workouts as he remains hopeful of getting a contract extension before July 15, the deadline to sign "franchise" players to multi-year contracts.
2.) How will Perriman and Pitta fare?: There are no two players who will be watched more closely this summer than wide receiver Breshad Perriman and tight end Dennis Pitta.
Perriman, the team's first-round pick in 2015, missed his entire rookie season because of a knee injury sustained in the first full-squad practice of training camp. Pitta also didn't play in 2015 as he continued his recovery from a twice fractured and dislocated hip, an injury that's limited him to seven games over the past three seasons.
If they remain healthy, the Ravens will start the season with more offensive weapons than they've probably ever had. However, there remains a curiosity and concern about both players.
Perriman was initially expected to miss a short amount of time with the knee injury, but he didn't respond well physically or mentally to the setback. He'll need to prove this summer that he can hold up and be the playmaker the Ravens envisioned getting.
Pitta fractured and dislocated his hip the second time on a non-contact injury. He's done a lot of work strengthening the area, but the risk of re-injury will always be there.
3.) What are the position battles to watch?: The major position battles won't heat up until training camp starts in late July. However, good first impressions can go a long way, and it's always interesting to get a look at the early-season depth chart.
At running back, Terrance West (Northwestern High, Towson), Lorenzo Taliaferro and Trent Richardson will likely be competing for just one spot behind Justin Forsett, Buck Allen and rookie Kenneth Dixon.
Smith, Perriman, Kamar Aiken, Mike Wallace and rookie Chris Moore are viewed as the roster locks at receiver, leaving only one or two openings for Michael Campanaro (River Hill), Keenan Reynolds (Navy), Jeremy Butler and Chris Matthews.
John Urschel remains the most logical replacement for Kelechi Osemele at left guard, but there are several other starting candidates.
On defense, the Ravens will start sorting out their various edge-rushing options, which include Za'Darius Smith and rookies Kamalei Correa, Matt Judon and Victor Ochi.
There's a job to be won at weak-side linebacker with Zachary Orr and Arthur Brown in the best position to seize it.
The Ravens also have spots to fill in the defensive backfield with veterans Kyle Arrington and Matt Elam, and newcomers Jerraud Powers and Tavon Young looking to make their case.
4.) Where will Stanley start?: Ravens officials have projected big things for offensive lineman Ronnie Stanley, the sixth overall pick in the draft. What they haven't done is say he'll be the team's starting left tackle in 2016.
With Eugene Monroe still on the roster and the coaching staff vowing to play the best five linemen, Stanley could be asked to slide inside to left guard, a position he never played at length. When that transition takes place depends largely on what the team decides to do with Monroe, the oft-injured veteran who has been a major disappointment since signing a five-year, $37.5 million contract with the Ravens before the 2014 season. His release still seems likely.
If Monroe was healthy and he attends this week's OTAs, the Ravens could have Stanley working either at left guard or with the second team. However, it might be a moot point as Monroe is still working his way back from shoulder surgery and he didn't attend the OTAs last year even though he was healthy. Monroe has already said on social media that he'll be on a forum about medical marijuana on Wednesday in Las Vegas, which coincides with the Ravens first OTA.
5.) What other rookies have the most to gain?: Because he's making the transition from a record-setting college quarterback to an NFL receiver, Reynolds may have the most to prove. Nobody expects Reynolds to be a finished product, but coaches will want to see steady improvement in his route running and other fundamentals.
Correa and Judon should get a lot of repetitions in the likelihood that Suggs and Dumervil won't be participating. Fourth-round offensive tackle Alex Lewis will get a chance to show his versatility and defensive tackle Willie Henry can start making a case for being a part of the team's rotation.
Dixon (hamstring) and third-round defensive end Bronson Kaufusi (back) were dealing with injuries at the rookie minicamp, so their level of participation this week is unclear.
