In 2003, Robert Mathis was just a fifth-round draft pick from a college no one had ever heard of before. Most people probably didn't even know he was on the team when the season started, after all, he wasn't even from a Division I school.

By the end of the year, Colts' fans knew the name Robert Mathis. Mathis compiled 28 tackles his rookie season, but most notably, 3.5 sacks and three forced fumbles. He was well on his way to becoming the Pro Bowler that Colts fans know and love today.

The Colts never draft "big name" college players. Chris and Bill Polian, with help from scouts and head coach Jim Caldwell, watch endless amounts of video on guys that will fit their system. So far, their philosophy has worked out pretty well.

Right now, most people probably don't recognize the names Ben Ijalana, Delone Carter or Drake Nevis. But you never know which of these Colts rookies could end up being the next perennial Pro Bowler.
