Who is the biggest threat left in Alabama in 2018?

Alabama is without a doubt the best university football team. The Crimson Tide has just won its fifth national title under head coach Nick Saban and looks if possible even better this season than last year.

As usual, Alabama has talent in all areas: size and strength in the trenches, a loaded depth chart of half-star 5 stars, incredible speed to his skill positions and, most importantly , Saban at the helm.

But the biggest difference is Tua Tagovailoa, who is arguably the best college football player, not to mention the SEC quarterback. Tagovailoa is the favorite to win the Heisman Trophy with 2066 yards, 25 touchdowns and no interceptions on 107 of 152 passes (70.4 completion percentage).

Last January, the replacement of the former 4-star candidate by the National Championship Playoff Football Championship pushed Alabama to come back from deficit 13-0 and defeat Georgia 26-23 in overtime. Unsurprisingly, the chemistry is even better with Tagovailoa having more experience in the game with the rest of the list loaded with the tide.

So what's left to stop the reigning national champions? Is there anyone who represents a legitimate threat to the scarlet tide?

Here is an overview of the most difficult remaining confrontations for Alabama in 2018:

@ No. 4 LSU– Nov. 3 / May 29th (Playoff Football League)

Few people expected LSU-Alabama to be as important as its pre-2018 rivalries. However, the Tigers exceeded expectations and placed fourth with several victories against ranked opponents.

Excluding a defeat on the road against Florida earlier this month, LSU dominated his entire program, including a home duel against Georgia, which was previously considered the biggest threat to the Tide in the SEC after the loss in January overtime.

While the Alabama should always be a big favorite, LSU is by far the best team on its calendar at any time of the season and the advantage of the Death Valley field should make things interesting. But again, it's hard to imagine that the tide stumbles in the regular season.

It is also worth noting that the Tigers would be the semifinals of Alabama College Football Playoff if the season ended today, so they are the solution for this match as well.

No. 7 Georgia or No. 9 Florida (SEC Championship)

The winner of this weekend's game between Georgia and Florida will likely win the SEC East and face Alabama under the title of the conference.

The Gators and Bulldogs are expected to win the rest of their matches after this weekend. Georgia would eliminate Kentucky from contention next week.

The Bulldogs gave Alabama its biggest threat of all games in the last calendar year, but last year's team was well above 2018.

Florida has managed to make the most of an easy schedule with the Eastern SEC and to shoot from a shock against LSU, but it is doubtful whether the Gators will be able to measure themselves favorably at the tide.

No. 2 Clemson or No. 3 Notre Dame (National University Football Playoff Championship)

Assuming that the latest College Football Playoff poll directly reflects the current AP poll, Alabama will face the winner of Notre Dame Clemson in the College Football Playoff semifinal.

Notre Dame has quality victories against Michigan – also a CFB playoff candidate – Stanford and Virginia Tech, and should be favored in her remaining regular season clashes. In addition, the Fighting Irish will have more time to prepare for the series without having to play a title of conference.

But Notre Dame did not face Alabama and it is likely that this confrontation will bring Fighting Irish back to Earth.

Clemson also has a favorable schedule remaining and has just won a victory over the no-then. 16 NC state. The Tigers have always faced Alabama in the final of university football matches, but fell flat in last year's semifinal.

That's probably what would happen if both teams faced each other in a rematch next January. Clemson's rookie, Trevor Lawrence, has been outstanding, but he's still a freshman and a duel against the tide could be overwhelming.

Alabama seems too strong for anyone to pose a credible threat to his chances of becoming a champion. These are the toughest games remaining and even they should not slow down the Tide's run towards his sixth title under Saban.
