I'd be fighting at 145, so he'd probably just manhandle me. Pound for pound, I see it like this: we start, I move in with good head movement, pumping the jab, finding my range, and working his legs with kicks. As soon as I see the opening, I shoot in for a single. If I get his leg, I run the pipe and drop him, if he manages to stuff me, I work up into the Greco clinch where the waltz begins, until I get either double underhooks and slam, or a leg trip. Before he even hits the ground, I'm working to pass guard. Eventually from pressure and technique, I pass his guard into full mount, where I start to drop fists and elbows until I either see the opening for a sub (armbar, americana, head and arm triangle etc), he rolls and gives his back up, or he get's TKO'd. Well, that's it simplified, but as you know, no plan survives first contact with the enemy
