Give it a year or two and Scott Quigg will be up there....
There actually seems to be a lack of top quality out and out pressure fighters today thinking about it.
Rios is big & strong, hits hard and keeps coming, he's durable too. He dont cut the ring off well though and takes too much on his way in
Miguel Cotto hasnt done the pure pressure fighter routine in a while but He knew how to cut off a ring and how to pressure behind a jab and solid defence, work the body over when he got there too. I think against the right opponent he could still do it but as a fan of his im glad he's gone more "Boxer" of late.
