How would it be cool?
How many times is this guy going to retire then return??
I can understand these guys wanting to play again, but they should've extended their careers instead of retiring early, and made better decisions. If they want to come back, come back as mentors to help the younger generation experience what they did.
Like Clyde or MJ can help Wade or someone like him. Dwayne Wade is my favorite rookie from last years class, and was my favorite over 'Bron and Melo before the draft even took place. I was glad he went to Miami, and he did well playing out of his natural position. I think he could benefit from learning from Drexler or Jordan, and I think that is exactly what they should do. He was the only younger player on the Olympic squad to take his role as it was without complaining.
