While i agree with your evaluation of Tackie wholeheartedly, i have to say i don't concur in relation to your comments reagarding Thaxton and Magee.
Thaxton is a fighter of a decent caliber, not outstanding in any one area, but a well rounded boxer and at lightweight he still posesses potential.
As for Magee, i never found him to be incredibly quick, even at the pinnacle of his career (which no doubt was the Hatton fight.)
Pep did possess some speed although his stamina was greatly diminished by the time he encountered Ricky.
