Here's a look at the top 5 players at each position as free agency gets underway ...
Top Five Quarterbacks
The veteran signal-caller is one of the best in the league in the right circumstances. When he stays healthy, Warner puts up great numbers (4,583 yards and 30 touchdowns in 2008).
Another veteran quarterback who had a big year. Knows how to get the job done. Won't be the right guy for every team, but he can get the right group to the playoffs.
Still a solid starter. Has problems staying healthy, but Garcia has posted a winning record in the games he's started in each of the last three years.
Former top 10 pick barely played in 2008. Leftwich is under 30, healthy, and still has the physical ability to be a good starter.
Losman had a terrific year in 2006. He's struggled in the last couple of years, eventually losing his starting job to Trent Edwards. Losman is still physically gifted and could be a good fit in a vertical passing offense.
