People are still going off of what Smith used to be, when the evidence would indicate he's not quite the player he once was.
Hate it, but it happens to all of them.
Just to touch on this...
People are also saying that he still has explosion, awful QB situations and is still as competitive as there is. Unfortunately any potential trading partner will look at the last two years and say, "wheres the production?"
4 months after becoming the 5th fastest player to reach 7,000 yards, Anquan Boldin was traded for a 3rd and 4th and received a 5th round pick, which amounted to roughly the 84th pick in the draft.
Now consider that Boldin then went on to be the fastest player EVER to reach 600 receptions. What major achievements has Smitty achieved beyond his triple crown in 2005? He hasn't even finished a season since then...
A little caveat. Smith gained more yards in 2005 than he has the past two seasons.
