In a finals-like match played in front of more than 50,000 people, Jamison started in his traditional spot at full-back and watched the Hawks pile on seven goals to one in the first half.
It was a tough re-initiation for the Blue who had spent almost two months on the sidelines nursing a knee injury.
"We just thought our first half, our forward line did not function as well as it should have, their backline was probably having a bit too much influence, so we spoke about that and we were able to rectify that in the second half," Jamison said after the match.
Also at the half, Captain Chris Judd had a simple message for his teammates.
"Juddy spoke to us and he said we could drop our heads and have a sook or we could respond in the second half and show that we can match it with the Hawks," Jamison said.
After the half, coach Brett Ratten moved his full-back to full-forward.
Jamison gave the Blues a target in the forward line and his defensive efforts helped keep the ball in attack, allowing them more opportunities. After their slow start, the Blues outscored Hawthorn seven goals to three in the second half, falling just short of a stirring victory.
Jamison said the move forward was something he had not experienced since his junior days.
"I haven't gone forward for five or six years. They just said 'give us a contest', and I tried to do that," he said.
In his 69th game, Jamison scored his first AFL goal midway through the third quarter.
It is the second longest stretch of games it has taken any current player to kick his first goal behind Richmond's Will Thursfield, who has played 74 games without a goal.
"It was a nice moment, but more than anything it will get the boys off my back, they have been continually reminding me that I hadn't kicked a goal, so it's going to be nice to put an end to that," Jamison said.
Friday night's loss has made it difficult for the Blues to grab a vital double chance in September, likely to be leapfrogged by West Coast on Saturday, but Jamison said the loss carried with it some important lessons.
"It's pretty simple, if you take your foot off the pedal at all, you get found out. Our first half was really disappointing but to our credit we rectified that," he said. "Taking your opportunities is so important, I think we kicked 1.8 in the first half, you can't do that in the finals and get away with it."
Despite his lay-off, Jamison said he was happy with his conditioning throughout the match.
"The knee is great, it is as good as I could have hoped for, there has been no swelling and the fitness was surprisingly pretty good as well," he said.
With the Blues having the bye next week, before facing St Kilda in round 22, Jamison will play in the VFL in a bid to gain more match practice.
"That game in the VFL next week will help, before playing the Saints in two weeks, hopefully three games before the finals should be pretty good," Jamison said.
Ratten was relieved his full-back got through the game without incident and was pleased with his efforts as a makeshift forward.
"He looked pretty dangerous up forward. He didn't kick the goals from all his shots but we might have to get more goalkicking practice into him," Ratten said.
"It was really encouraging to get him up there, it was just good to get him into the game and get through unscathed so we can move on."
