What if Ray "Boom Boom" Mancini and "The Bubblegum Bomber" Sean O'Grady met in 1981?

Mancini could really fight, O'Grady was promoted by his own father and bought along easy.
At only 19 years old Mancini went up agianst a prime Alexis Arguello, and hung in tough till 14th. He beat Ramiriez, and should have gotten last decision with Bramble, although even if decison was right, I can't see O'grady hanging in more than few with fighter of that caliber.
