The rugby world has reacted in wonder to Barrett's play, and Jacobson said he was lucky to 'clean up the scraps' after Barrett's run at the line.
"I saw Baz having a bit of a run at the line, and I saw him have a quick glance out to me, so I knew he knew I was there. Then I thought he had taken the contact, and he was just going to take it down there.
"But then he rips one out the back and I think it was a better pass out the back than I could do normally. It was top shelf from Beauds," he said.
Barrett was one of several players in the team who required team-mates to be ready for the unexpected, and it was a case of anticipating and ready for an offload by being in the right place at the right time, he said.
Jacobson said he enjoyed the game. It had been good the All Blacks came out firing and were able to 'knock them on the nose' from the outset.
"We didn't let them get their tail up which helped us a lot, and we got to hold onto the ball for a lot of the time as well. They started to get a bit tired which took away from the physicality and the niggle they like to bring.
"I enjoyed the game and it was good to get out there and get some minutes as well," he said.
Having had his frustrations with injuries, notably being forced home from the 2019 Rugby World Cup without playing a game, Jacobson said he has enjoyed 2021 and getting game time. While it was good to get back into the game, it was better to contribute on the field.
Consistency of time at No8 had been enjoyable, but he was still covering the blindside of the scrum while also covering the open side, all of which he enjoyed.
"I'm still ready to jump in if need be, but it's just happened that I've been brought on at No8 each time. Eight has been enjoyable although I didn't quite get it right last night a few times off the back of the scrum," he said.
Having fellow Chiefs lock Brodie Retallick back after his two-year stint in Japan was positive.
"He's a special sort of player, he's someone who keeps on going, he's into everything.
"If you just watch him go round the field, he's got a serious amount of ticker to him. He's not going to let the foot off the pedal any time, he's supporting all the breaks, getting right into the defence. He's a wicked player to play with and feed off as well…he's quite inspiring," he said.
