Tee Martin has been watching Lamar Jackson long enough to know that the Ravens’ star quarterback is capable of making the game’s hardest throws. And he’s been coaching long enough to know that the game’s hardest throws defy simple instruction.

“There’s no one way to throw a deep ball,” the Ravens’ quarterbacks coach said Tuesday — especially when the quarterback is as talented as Jackson.

Still, the Ravens are going back to work on the long ball this training camp. On passes of at least 25 air yards last season, Jackson went 14-for-46 (30.4%) — the league average for the throws, according to TruMedia, was 31% — with three touchdowns and two interceptions. His off-target rate (41.3%) was the fourth highest among the 20 quarterbacks with the most downfield attempts.

Jackson’s deep passing gave the Ravens’ offense a spark in their AFC championship game matchup with the Kansas City Chiefs. Then it all but ended their season. He hit wide receiver Zay Flowers for a 30-yard touchdown in the first quarter, then found Flowers wide open again for a 54-yard gain late in the third. But Jackson went 0-for-4 on passes of at least 25 yards in the fourth quarter, including his interception into triple coverage as he looked for tight end Isaiah Likely with the Ravens down 10.

“You’ve got to let it rip,” Martin said of his approach to Jackson’s deep passing. “You can’t get into the head of the thrower — you just can’t, you just can’t. You just keep getting reps with those people, and so many things are variables there. Did he get moved off his spot in the pocket? Was it a clean release? … So you don’t make any excuses; you just go at it again and just keep trying until you get perfection, and that’s what we’re all trying to reach. ... The whole season, you never peak until your last rep of that season, but we’re always chasing that.”

The Ravens should have the speed to stretch the field. Wide receivers Rashod Bateman, Devontez Walker and Flowers all ran the 40-yard dash in 4.42 seconds or faster at the NFL scouting combine. All three were big-play threats in college. All three have made big catches in camp.

The goal now for offensive coordinator Todd Monken, with the Ravens’ season opener five weeks away, is to get everyone synced up and everything schemed up. Jackson has completed a handful of downfield passes in his three full practices, including touchdowns to wide receivers Tylan Wallace and Flowers. But against the Ravens’ stalwart secondary, there have been struggles, too, including several overthrown passes.

That’s what camp is for. Jackson needs the work, but so do the Ravens’ receivers, and their offensive line, and their coaches.

“At the end of the day, it’s just about ball placement, timing, separation from the receiver — it’s a lot combined in that,” Martin said. “And that’s just all we’re chasing. There’s no one thing you can say. ... I threw a lot of [deep passes] myself. All of them were different, all of them are based on the things I just mentioned, and you just want to keep working to where you can get as many of those variables out of the way as you can, to where you can diagnose it. And that’s what training camp and preseason is all about.”

Said Monken: “We do have to be able to be more explosive. We do have plenty of speed. Now we just have to be able to utilize and scheme it.”

Attendance

Ravens wide receivers Rashod Bateman, Deonte Harty and rookie Devontez Walker missed practice. Harbaugh said after Monday’s practice, which Bateman left early and Harty missed, that the two were dealing with soreness.

Also missing were defensive lineman Rayshad Nichols, outside linebacker Joe Evans, undrafted rookie inside linebacker Yvandy Rigby and cornerback Trayvon Mullen (shoulder). Running back Keaton Mitchell (knee), rookie outside linebacker Adisa Isaac (hamstring) and rookie cornerback T.J. Tampa (sports hernia) remain sidelined.

Stock report

• Tight end Isaiah Likely and safety Kyle Hamilton had another busy matchup. In a half-field-read passing drill early in practice, Likely and Hamilton traded early wins. Late in practice, Hamilton stuck to Likely during a red-zone route, but with the safety not fully turned to the ball, Jackson placed his pass where only the tight end could get it. Likely celebrated the touchdown with a mock skeet shooting demonstration.
• Quarterback Josh Johnson capped the Ravens’ final red-zone drill with two touchdowns and — a near interception. After finding wide receiver Sean Ryan, who had a strong day, on a crosser, he hit wide receiver Malik Cunningham on a slant against cornerback Arthur Maulet for another score. Rookie cornerback Nate Wiggins broke up the next two passes, though, stopping an in-breaking route by wide receiver Nelson Agholor and stepping in front of a red-zone pass to Andrews, only to drop the would-be interception.
• Inside linebacker Chris Board had the Ravens’ lone interception, bringing in a deflection off wide receiver Dayton Wade’s hands after an apparent miscommunication between the undrafted rookie and Johnson on a short throw. Board likely would’ve scored on the return.
• Without full-contact hitting, running games — and running backs — can be tough to evaluate in training camp. But the Ravens had a handful of carries reach the second level Tuesday. Derrick Henry bounced one run down the left sideline, Owen Wright found a lane up the middle and Justice Hill weaved his way through the defensive front on one zone run.
