Its not ridiculous at all. I can also easily say Fitzgerald is a much better player then then Gandy. They play different positions but its a pretty easy statement to say.
Who cares about positions, its called comparing "FOOTBALL" players. You cant compare stats but its pretty easy to compare football players, not sure why your throwing such a fit about.
In the future we shouldnt see you ever compare players ever again, becuase you aparently cant unless they play in the same exact scheme, same exact personel around them, and so on. Heck with that critiria in mind how can you compare players that play the same position unless they have both played in the same exact scheme or played with the same exact players.
Its called comparing "FOOTBALL" players and its easy to, scouts do it every year when trying to make a draft board.
Dansby and Suggs have both had excellent careers. Therefore you have to take into consideration where they play and what team they are on. Suggs would have likely never had the same success playing DE in a 4-3 for Arizona as he did in Baltimore. See Calvin Pace.
In almost every discussion about players on this board one or more people bring up the effects of what team a guy is on or who plays next to him. Its far more common than people debating who is a better player a WR or an offensive tackle. I'm sure the latter goes on all the time at sports bars across the country.
In fact looking for a guy who hasn't done much because he is on a weak team or playing behind a perennial pro bowler, or in the wrong scheme, is something scouts do all the time when making a list for free agency.
And what's your definition of "FOOTBALL" player. In your Gandy and Fitzgerald example how can you say who is better? Fitz would be a terrible football player at offensive tackle. Do you really think Fitz would be a better OT than Gandy? Position does matter.
And I still think its ridiculous to say that Suggs is a far better player than Dansby. He might be better. He might not. But the difference is not as huge as you make it out to be.
