ooh nice thread - only one?
1970's: Jim Zorn
1980's: Kenny Easley. Largent is a REALLY close second, and he definitely belongs on this list somewhere. But growing up Easley is the player I waned to be: roaming safety ready to tackle and intercept
1990's: John L Williams 
Kinda cheatin' here, since he's really an 80's guy. But I identified with him on offense - multi-talented fullback that ran, caught, and blocked. And I didn't really identify with many of the 90's players
2000's: Mack Strong: didn't identify with many in the 2000's really, kind of fell out of touch, however love his story about really grinding out his career, especially the resurgence the second go around and fantastic lead blocker
2010's: Earl Thomas. He inspires me because he's his own unique character, in his own mindspace, and not afraid to show it. Not to mention the way he plays, especially for a guy his size, he's all heart. The only guy who probably would ever be able to make eye contact with Marshawn and Marshawn looks away first
Favorite all time though is probably Largent. Crafty, very skilled at his trade, not the most athletic and yet always found himself open relying on his skill and craft. One of my favorite quotes "If they are looking at my eyes, then I know they're not looking at my feet"
Plus his longevity
Plus his consistency
