We've noted that the Harbaugh coaching tree is growing, and that Willie Taggart goes back to Jack's WKU days, then worked for Jimmy at Stanford. Not terribly detailed, but there's some nice analysis here, including gifs, of how Taggart's conceptions of how to run an offense have evolved, working to his best players' strengths, through time.
Long story short (to my limited understanding), Taggart plans to move the ball quickly, simplify the offense, move away from Fisher's highly complex style, toward a spread offense with some play-action concepts. Still traces of what he assimilated at WKU and Stanford in his method, but Taggart sounds like he's highly adaptable, very much his own man. The reception in Tallahassee has been very enthusiastic, and it's well-known he can recruit. Don't be surprised if FSU returns to prominence quickly.
