From his appearance last Monday, I don't think Bret is in any kind of ring shape - nor will he be by WM.
I've always liked the Hitman and I really enjoyed seeing him last week.
But, as far as him getting in the ring (I'm sure he will), don't expect to see the old "excellence of execution."
Between his stroke, the concussion(s), weight gain, and Father Time, Bret's glory days in the ring are long behind him.
That being said, he still knows how to "work."
He still knows how to tell a story in the ring using his body, timing, psychology, and acting.
And whatever he does "in...this...very...ring," you can rest assured it will be top-notch!
