I dig it, but there are still other great fights at 140. Khan/Matthyse, Khan/Garcia II, Matthyse/Rios, Garcia/Rios, Matthyse/Judah II (yeah, yeah, I know), Matthyse/Pederson, Garcia/Pederson, Bradley/Matthyse, Bradley/Garcia, if Bradley ever decides to come back to 140, which he should, or Garcia/Marquez.
All are very valid fights. Garcia/Matthyse should be the fight at 140 for the foreseeable future, but there are still many great fights possible.
I hope that Garcia/Matthyse gets done after Judah. If Judah somehow beats Garcia, we'll have Judah/Matthyse II. Then I'd love to see Matthyse/Rios.
