When I listen to older material I am simply amazed at the fretboard gymnastics Red used to pull off, but the plain and simple truth is dude got older.

There is definitely truth to this, which only makes complete sense. Besides being musicians, there is athleticism involved in what they do. Just briefly, off the top of my head, I would point to things like Ventura 98 Hood or Denver 97 Ghost as examples of dexterity that is possibly out of reach for Trey at this point. HOWEVER, all coins have two sides. There was an almost machine-like precision to his playing in those days...whereas now I would, dare I say, often hear something really soulful in his playing...maybe even something more important than mind-boggling speed on the fret board.
