Team went 12-2 and 11-2-1 in the two years Jackie Burkett was on the team.
He played in 3 games for Dallas in 1968, then played 11 games for the Cowboys in 1969.
There aren't any stats on tackles available at NFL.com prior to 2001, so no stats are available for him besides several interceptions he got when he was with the Colts and the Saints. He played 5 seasons for Baltimore from 1961 to 1966. In '67 he jumped to the Saints, and had a great year for them, appearing in all 14 games and getting 3 interceptions.
In 1968 he jumped to Dallas, stayed for the '69 season, then went back for his final 10th year in the league with the Saints in 1970, grabbing 4 interceptions over 14 games.
RIP, Jackie Burkett!
