It matters in that 140 would be the most one sided. Whitaker was brilliant at 140 against Pineda. He beats the shit outta Miggy at 140. At 147, Cotto has some moments here and there, but loses wide. Like 10-2, or BEST case, 9-3. At 154, Cotto has a few more moments, but still gets outclassed. Like 8-4.
