This has probably been hashed over before, but Massey doesn't actually drop his elbow like he recommends on the first shot at the beginning of the video. It does appear he drops it a bit more at the end of the video.
Unfortunately, from a fan's perspective, this is all too correct.
But in defense of the modern top players, they HAVE to "play like robots" to win.
The competition is just too good, the tables are faster, and the pockets are smaller.
You can't be "loose" anymore if you expect to succeed at the top level.
