Personally, I don't agree with the sentiment that Pettis is a bad matchup for Ferguson. In fact, I think there's a argument that the opposite is true. Yes, Pettis has struggled with guys who can grind/take him down. But, he also doesn't deal with pressure well, has a tendency to get backed up to the fence and isn't nearly as effective off his back foot. He's also shown a tendency to slow down later in fights. Ferguson brings more pressure and pushes a higher pace than maybe anyone else in the division.
I think the argument for Pettis here is more based around Ferguson's tendency to be reckless at times. Pettis is so sneaky with his submission game and Ferguson definitely puts himself in dangerous spots.
All that said, I do agree that at these prices Pettis is worth a small play. I opted to play his scorecards = no action line at +333 over his ML since I think his chances of winning a decision here are pretty low. I also stabbed his sub line at +1235.
