We're looking at seven key storylines to watch as the Baltimore Ravens take the field for seven OTA sessions and a three day minicamp in June

The NFL announced its nine-week offseason workout routine for all 32 teams back in April, and the Ravens will now take the field for the final sessions of Phase Three, with up to ten days of organized team practice activities, or “OTAs.”

The training programs are divided into three phases: one mandatory minicamp for the entire roster and one rookie minicamp for each group.

No live contact is permitted, but 7-on-7, 9-on-7, and 11-on-11 drills are allowed.

With OTAs kicking off on Tuesday, we're looking at seven storylines to watch.

OTAs, Mandatory Minicamp

The OTAs are divided into phases, and the Ravens will convene for on-field sessions seven times before the mandatory minicamp: May 27-29, June 3, June 5-6, June 9-12. There will be three days of mandatory minicamp, from June 17-19.

More Todd Monken

Last season, the 28-year-old Jackson set career highs in touchdown passes (41), passing yards (4,172), and quarterback rating (119.6) while throwing just four interceptions. Monken is entering his third season coaching Jackson and expects the quarterback's growth to continue and reach another level as he enters the prime of his career.

Under Monken, the Ravens offense led the NFL in both rushing yards (3,189) and yards per rush (5.8) this past season.

Roster battles

The Ravens won’t have too many starting spots up for grabs, with left guard, linebacker, and safety being spots that'll see potential roster battles.

Andrew Vorhees lost his starting job to Patrick Mekari last year, but he's back and will battle again, and is the favorite to start at left guard. They re-signed veteran Ben Cleveland and drafted Emery Jones and Garrett Dellinger. Trenton Simpson will battle Teddye Buchanan and Jacob Hummel. At safety, Malaki Starks has the inside track as a rookie, but the Ravens like to employ three safeties, and Beau Brade could battle Sanoussi Kane for the spot vacated by Ar'Darius Washington.

Who will show up?

Only the minicamp is mandatory, and the Ravens don't fret when their stars aren't in attendance. Lamar Jackson, Kyle Hamilton, and others all missed time last summer, and the same could happen with Mark Andrews, Isaiah Likely, and other potential free agents or players with contract issues. Jackson, for his part, is looking for a new contract, and staying away until the practices and games count is a viable tactic for a player with a $43.5 million cap hit that rises $30 million over the next two years.

Rise of a new kicker

Justin Tucker is out, and for the first time since 2012, the Ravens will have a whole competition at the kicker position. Sixth-round pick Tyler Loop will battle undrafted free agent John Hoyland from Wyoming. It's a premium position, and one of the few question marks on a team with Super Bowl aspirations.

Rookie impact

Malaki Starks and Mike Green are the headliners, and with Ar'Darius Washington's Achilles injury, the first-round pick from Georgia will be the main attraction. Starks is a Swiss army knife that should hit the ground running, allowing for Kyle Hamilton to be even more versatile. Fourth-round inside linebacker Teddye Buchanan will battle Trenton Simpson for the starting weakside linebacker job. Sixth-round cornerbacks Bilhal Kone and Robert Longerbeam and sixth-round defensive lineman Aeneas Peebles will look to prove they deserve a role in Zach Orr's defensive rotation.

Cooper Rush

Baltimore has a new backup quarterback after agreeing to a free-agent deal with former Cowboys signal-caller Cooper Rush. According to ESPN's Adam Schefter, the two-year, $6.2 million contract can reach $12.2 million.

Baltimore's backup quarterback for the last two years was Josh Johnson, but he signed with Washington. Former Kentucky quarterback Devin Leary will be the third quarterback on the roster, and the Ravens could bring in competition for that spot. Rush has won nine of 14 starts in his career, putting him near the top of the backup market. Last season, Rush replaced an injured Dak Prescott (hamstring) from Week 11 on, tossing 12 touchdowns and four interceptions while averaging only 6.1 yards per attempt.
