I think less of Lemeiux than most people on this thread but I think he wins convincingly against de la Rosa. I would predict a Lemieux TKO5.
That would be conventional logic, given that King James has been down 5x (vs. Conyers, Brunson & Centeno Jr.) and was badly hurt and nearly dropped by pedestrian Troy Wilson - but even so, his chin held up for ten rounds with Perro Angulo, who is probably stronger physically than Lemieux and less crude but not by a ton...and DLR pulled out the W. :think
