Best bets for UFC 257: Dustin Poirier vs. Conor McGregor 2

Conor McGregor makes his dramatic return (again), but this time it's to take a rematch against a previously defeated opponent, without access to a viable title shot. In his 2014 fight against Dustin Poirier, McGregor closed as a roughly 3-to-1 favorite -- which is where he hovers during this current fight week -- despite having opened at a far more affordable number. This scenario is nearly identical to McGregor's last fight a year ago, where he knocked out Donald Cerrone in a first-round stunner. But where Cowboy Cerrone was already into a late career slide, Poirier has continued to impress and is getting better and better. So, the odds here might look familiar, but the trajectories of the matchup are very different.

Early prelims are at 6:30 p.m. ET Saturday on ESPN+, prelims begin at 8 p.m. ET on ESPN/ESPN+ and the main card starts at 10 p.m. ET on PPV.
