I believe Ted Thompson has a unique eye for talent coupled with a silent, efficient workrate. Teddy has always said he will go through the "build through the draft" route - you can't expect someone to earn a reputation and respect around the league without being supremely proficient in their own philosophy.
Now, if Al Davis says "We like to build through the draft" - you'd turn around and tell the senile ol' man to give up his draft picks for established players. Ted Thompson is one of the best drafters in the league at the moment. Aaron Rodgers, Greg Jennings, Nick Collins, Jermichael Finley, Josh Sitton - all pro bowl caliber players.
I don't think it can be limited to drafting either - low pick trades such as Ryan Grant for a 6th and grabbing Tramon Williams sfter he got cut by the Texans - great moves.
Justin Harrell can be seen as one of his few failures, but really?
Is all fault to be placed on Ted Thompson?
He looked like he could be a player before he got the injury against the Eagles - not only that, but the injury wasn't even related to the chronic back problem.
He is more a bad luck case than a bust.
Zero2Cool is my captain.
