The Left Wrist Uncocks only to the Level position (where you still have #3 Accumulator) during Release. If you reach fully Uncocked before Impact, watch out for that Horizontal Left Wrist Bend, because that is what is going to happen at Impact. I see it over and over again; Over-Loading, Over Accelerating, Steering .
Differentiating between Uncock and Roll (study 2-P, 4-D-O, re-read them now) goes back to Educating the Hands thru the Pressure Points and practicing the Drill Mr. Kelley put at the end of 4-D-0; both done on the same Delivery Line, driving the ball into the ground, not toward the green. Do it first without a club, then with dowels, then with a club, with eyes open (look, look, look,) then with eyes shut. Over, and Over, and Over; Alignments, Pressure Points, Rhythm, Pace, Acceleration. Let the Mechanics produce the action, the Feel reproduce.
BTW, the Right Wrist is never Cocked and never Thrown.
