Indianapolis Colts: 15 best free agent acquisitions of all-time

D’Qwell Jackson was brought in as an older linebacker. He was 31 years old when he came in from the Cleveland Browns. He spent three years in Indianapolis, and those were actually the last three years he spent in the NFL.

Jackson had the best year of his career in 2014, his first year in Indianapolis. He had a career-high 167 tackles, a career-high four sacks, and a career-high four fumble recoveries. He even scored the only touchdown of his long career on one of those fumble recoveries.

Jackson made the Pro Bowl that season. But he was never quite able to recreate that amount of production in his other two years. The Colts needed that production in 2014, as they made the AFC Championship game that year. Jackson was a big reason for that.

In the last year of his career, he missed four games due to suspension. His production wasn’t nearly as good as it had been in the two previous years, and his age had begun to show. He was soon released and was never picked up by another team, eventually retiring.

Even though Jackson’s time with the Colts was short, his production was great. Not only that, but he was voted a captain because of his great leadership. He was an important part of that AFC Championship playing team. The next person on this list was important to the Colts too, but on the offensive side of the ball.
