YES!
I was wondering just this afternoon what was it that turned it around for Carroll from his first stint in the NFL.
After having success at USC, I think he gained alot of experience in figuring out what it takes to make a successful college program. That first stint in the NFL probably humbled him in some ways and he learned from it.
The greatest human accomplishments in our history have come from making mistakes. Have you ever seen the MJ Failure commercial video?
Much like Jimmy, I think Carroll had a good knowledge of college prospects from his experiences at USC. He knew the players to avoid, like S Taylor Mays, and he also had a clear philosophy that he stuck to in getting his type of players.
I'd also say that he benefited from a good situation to step into as well. He pretty much got a clean slate when he took over the Seahawks and he didn't have some lunatic owner/GM micro managing him as well.
