Butler's career has had an interesting trajectory. He was a pretty high draft pick in 2006, when the Carolina Panthers selected him in the third round. He never played a down for the Panthers and was released before the start of the following season.
Butler has been a member of the Houston Texans for the past six years. He has only started four games during that stretch, though, which came during the 2010 season. Last year, he was competing for a starting role at right tackle, but lost the competition. He has had a lot of misfortunes injury-wise over the past two years, tearing his triceps twice, which has forced him to miss 30 of his past 32 games.
The Browns can bring Butler in to see if he can revive his career, as he will compete with the likes of Oniel Cousins, Garrett Gilkey, Ryan Miller, and Chris Faulk for a backup offensive tackle position behind starters Joe Thomas and Mitchell Schwartz.
