Why It Matters: Over the last several years, interest for TUF has drastically decreased, so the Latin America finales tonight are little more than filler for most fight fans.

The real importance of UFC Fight Night 78 is the fact UFC has once again brought a show to Mexico, which is quickly becoming a burgeoning market for mixed martial arts (MMA).

The show features several Mexican nationals, and you can expect the crowd to be in a fever-pitch from the first fight on.

The fights themselves may not be all that important in the grand scheme of things, but you can bet the Mexicans in attendance will make this FOX Sports 1 event feel like the most important pay-per-view (PPV) of the year.

What's Hot: Neil Magny.

Nobody expected any contestant on the loathed TUF 16 would turn out to be a quality UFC fighter, and Neil Magny was well on his way to being cut by UFC brass after dropping two of his first three UFC fights.

Then suddenly, everything changed.

The lanky Welterweight got back in the gym, and worked his tail off to become a legitimate contender. After seven straight victories inside the Octagon, Magny was forcing fight fans and UFC brass to take notice.

The Illinois native never backed down from a challenge, and quickly became one of the most active fighters on UFC's roster, filling in on short notice whenever necessary.

It is apropos Magny will be stepping into the Octagon tonight on short notice to battle Kelvin Gastelum, in what will be his 10th fight in the last two years.

Magny is 8-1 in that span, and currently sits at No. 13 in the UFC rankings. Even with exceptional performances in the last 24 months, fans still doubt Magny has the tools to defeat the plethora of elite fighters at 170-pounds, but a win over Gastelum tonight would prove his doubters wrong once again.

What's Not:

This card is pretty weak overall, but nothing grinds my gears more than having the TUF finales on the main card.

TUF: Latin America 2 was not shown on national television in the States, but was instead relegated to UFC Fight Pass. Yet, UFC brass insists to have relatively unknown fighters showcased on FOX Sports 1 tonight over a fighter like Erik Perez.

It is truly baffling.

Point blank: very few fight fans care about the TUF finales, and it would do no harm to have both fights occur on the "Prelims" instead of the main card.

Original Card vs Actual Card:

Another UFC event, another main event lost.

Matt Brown was supposed to throw down against Kelvin Gastelum tonight in what would have been a sure-fire brawl, but an injury to "The Immortal" one forced UFC brass to call up Neil Magny once again to save the day.

The only other change on the card was Damian Stasiak being replaced by Taylor Lapilus to fight the returning Erik Perez.

New Blood:

Vernon Ramos vs. Alvaro Herrera: Two contestants from TUF: Latin America 2 will battle for a UFC roster spot tonight on UFC Fight Pass. Ramos is a submission machine, while Herrera is the more well-rounded fighter.

Erick Montano vs. Enrique Marin: The Welterweight TUF finale features a Mexico vs. Spain battle. Erick Montano will fight in his backyard hoping to become a TUF champ, while Marin will look to procure his sixth career submission finish.

Enrique Barzola vs. Horacio Gutiérrez: The Lightweight TUF finale features a Mexico vs. Peru battle. Barzola has fought most his career at 145 pounds, so expect him to drop down regardless of tonight's outcome. As for Gutierrez, "The Punisher" will look to earn another finish en route to becoming a TUF champ.

How The "Prelims" Look: Very mediocre.

UFC Fight Night 78 is painfully thin from top to bottom, so we are definitely grasping at straws here, but the "Prelims" do offer a handful of fighters you will likely want to watch.

The always exciting Andre Fili opens up the FOX Sports 1 "Prelims" at 8 pm, and you can also watch Scott Jorgensen battle Alejandro Perez in the very next fight.

The only must watch fight of the "Prelims" features the return of Erik Perez as he battles up-and-coming prospect Taylor Lapilus.

Who Needs A Win Badly: This portion is reserved for fighters who could be fighting for their jobs today, rather than contenders or title challengers needing victory. Let's take a look at those who need to pull it together:

Scott Jorgensen (vs. Alejandro Perez): "Young Guns" has been on this list nearly every time he has fought on a UFC card since 2013, but after going 1-5 in his last six bouts, tonight is likely his last opportunity to keep his roster spot. Jorgensen has lost two straight, and UFC brass is offering up a softball of an opponent to see if the former WEC contender has anything left in the tank.

Interest Level: 3/10

Outside of the main event, there is very little that gets me excited for UFC Fight Night 78.

A lot of fans will be pleased to see Diego Sanchez back in action, but I am flabbergasted at the choice UFC matchmakers made by pitting him against former No. 1 contender Ricardo Lamas in his 145-pound debut. Talk about getting fed to the wolves.

Other than the main event, I recommend catching Erik Perez's fight, and sticking around to see if Henry Cejudo can earn a UFC title shot by defeating Jussier Formiga.

Hopefully we are treated to some exciting fights!
