Jake Long is a bad example to use. The guy has been injured the past 3 or 4 years. He only started missing games this year because he's a tough guy, but he's definately on the decline. You don't pay injury prone players on the downsides of their careers. At 27 he should be entering his prime, but it's just not the case. He's had back issues, torn biceps, Foot issues, hamstrings, and I'm sure I'm missing a few.
2 years ago Jake Long had a down year, but could still be considered a top 10 tackle. Last year Jake Long was no more than average, and probably worse. I still think if you have an elite left tackle, most teams will pay him. And the fact that 3 are likely going in the top 10 this year shows how much the nfl does value them. Dumb article.
