Yeah, but Conor also has only ever fought two times at lightweight.
When he fought at welterweight, he faced Diaz, who by all means is no top-level fighter, with all due respect, and as mentioned, Cerrone was already pretty shot when Conor faced him.
Other than that, Conor either always outsized his opponents, or they were green (Poirier).
I agree though with Poirier being better than any of Fergusons opponents, with Justin not entirely, although it could be the case.
Yeah, Ferguson isn't exactly young, but so far i did not notice him slowing done and/or getting more prone to damage in his fights, although that probably won't be the case for too long, yeah.
I'd like to see Tony face these guys as well, maybe it'll happen, let's just wait and see.
