Here's a look at the top 5 players at each position as free agency gets underway ...
Top Five Offensive Tackles
Good pass protector, but only a limited run blocker. Will be entering his 12th season in the NFL, but Thomas remains a good starting left tackle.
Veteran right tackle emerged since Sean Payton took over the Saints.
Struggled with injuries in 2008. Quality left tackle when he's healthy.
Can be an effective starter, but Harris is nothing special. Has started on both sides. Excellent size.
Good run blocker got to start 10 games this year. Struggles with speed rushers. Will be of interest to teams that like to run the ball. Could also play guard.
