Kirk Lowdermilk is not a name many modern Colts fans know, but they should. He spent the last four years of his NFL career in Indianapolis and helped solidify the offensive line. He was a center that perhaps had the four best years of his career while with the Colts.
Lowdermilk came over from the Minnesota Vikings after having spent his first eight years of his career there. While in Indianapolis, he played from 1993 to 1996. He was the centerpiece of an offensive line that played pretty well and made two trips to the playoffs over that four-year span.
The Colts were a middling team in those two playoff years, going 9-7 in 1995 and 8-8 in 1996. But in the playoffs, they were a different team. They were able to play together and win some games, making the AFC Championship in 1995. Lowdermilk was a big part of that.
Lowdermilk started every game he played for the Colts, never missing a single game. He was durable, tough and was going to play hard every single down. Those are the qualities you need out of an offensive lineman, especially your center.
Although the Colts got him at the end of his career, he was still able to be very productive. The next player on the list can say the same.
