The Vikings' youth showed during Sunday's 20-17 loss to the Buccaneers.
There were growing pains like when safety Jay Ward was flagged for offsides on a Tampa Bay field-goal attempt, giving the Buccaneers a new set of downs that led to a touchdown.
Bright spots also appeared, such as rookie receiver Jordan Addison's 39-yard touchdown catch in the second quarter. Addison took advantage of Tampa Bay's double coverage on receiver Justin Jefferson and outran Buccaneers safety Ryan Neal on a go route.
"I really enjoyed that moment, cherished it, every second of it," said Addison, who had four catches for 61 yards and a score. "I hope — well, I know — there's going to be many more plays I make like that."
Five Vikings rookies made their NFL debuts on Sunday: Addison, Ward, cornerback Mekhi Blackmon, linebacker Ivan Pace Jr. and cornerback NaJee Thompson. Fifth-round quarterback Jaren Hall suited up, but did not play as the emergency third passer.
Addison, Pace and Blackmon handled the biggest roles. Blackmon, a third-round pick out of Southern California, entered the game as an outside corner in pass-focused subpackages. He was commended by coach Kevin O'Connell for his defense on Buccaneers receiver Mike Evans, who failed to come down with a first-quarter deep throw that Blackmon was closer to catching.
"Mekhi made a nice play down the right sideline," O'Connell said. "Jordan obviously showed up. There were a couple other plays where we just had some mental errors in some different spots."
Blackmon was also closest to Buccaneers receiver Chris Godwin's game-sealing catch that converted a third-and-10 play and allowed Tampa Bay to run out the clock.
