Manny Pacquiao vs. Lucas Matthysse

I feel like the poll for Pacquiao vs. Crawford will be a lot closer, and while I think Crawford rates well ahead of Matthysse at this point at 140lb (h2h and on recent form & deed) I'm not sure he's that much bigger a threat for Pac specifically. Nothing in Crawford's arsenal packs the raw dynamite of Matthysse's straight right hand, nor are his weapons as equipped to wreak havoc on a quick bunny-hopping in-and-out southpaw. Crawford's switching and "boldly aggressive but still careful and defensively sound" counter-punching style is perfect to frustrate and confuse most orthodox fighters (be they brawlers or cuties, as Bud has proven capable of handling both)...I'm just not sure he will be as successful when faced with Pac's own speed, and the last real southpaw he faced was Andre freaking Gorges...
