He just got lucky. Just like he was lucky when Rodgers, Mathews, Nelson, Cobb, Bakhtiari, Linsely et al. were all available. He's just a lucky guy.
Obviously, nobody is only good or lucky. There are lots of TT picks/moves that turned out great, as well as many that didn't.
Took me a while to go back to the original contention, but it was apparently about Woodson, in which case TT was good in recognizing there was still a lot left in the tank and lucky in that nobody else was throwing big bucks at him, in which case I doubt if the Pack lands Charles.
As for your list above, if TT was so sure that AR was going to be a savior, would he not have traded up to make sure he got him (ala Matthews)? I remember thinking that the pick was a good one in that Favre was already making noises and AR had been tossed around as either the top pick or #2. TT was good in that he DID pick Aaron, lucky that nobody else was thinking my/TT's way.
Matthews was an excellent pick, at least then, but TT made one of his few trades up, forking over a sizable payment. Too many unknowns (how far did he have to jump, how much did he have to pay) to really decide on lucky or good, but at least the talent evaluation was good.
Nelson and Cobb were both 2nd round choices, with Nelson being TT's first that year. I don't see getting a really good receiver out of those positions as either lucky or good, just something to be expected (and, depending on Cobb's recovery from a very pedestrian year so far, given his contract, maybe not all that great, anyhow).
Bak and Linsley, and a number of others, having certainly outplayed their draft status. Probably have to go with 'good' for those kind of players, but we've certainly hashed over the number of high choices that haven't turned out well, and does TT end up as 'bad' or 'unlucky' for those?
