The Kansas City Chiefs may have had the NFL's most explosive offense in 2018, but the offseason has not been kind to Andy Reid's club.

The Chiefs had already lost running back Kareem Hunt due to an off-the-field incident, as Kansas City released him back in November after a video of Hunt assaulting a woman at a Cleveland hotel surface.

Then, this offseason, wide receiver Tyreek Hill has gotten himself embroiled in child abuse allegations, and it's entirely possible that Hill does not suit up at all for the Chiefs this coming season as a result.

So, outside of tight end Travis Kelce, where are Patrick Mahomes' weapons in what was once a lethal Chiefs offense?

Enter Sammy Watkins, who takes over as the team's No. 1 receiver in Hill's likely absence and will then consequently serve as Kansas City's biggest X-factor going into 2019.

No, Watkins isn't Hill, but he is a guy who was chosen by the Buffalo Bills with the fourth overall pick of the 2014 NFL Draft for a reason. On the other side of the coin, we can then say that Watkins is already on his third NFL team for a reason, but he is just 25 years old and is now playing with one of the best quarterbacks in football.

Remember: back in 2015, Watkins hauled in 60 receptions for 1,047 yards and nine touchdowns in just 13 games, and that was with Tyrod Taylor throwing him the football.

Just imagine what he can do as Mahomes' top target in Kansas City?

While many are penciling in the Chiefs as a Super Bowl threat, people tend to be forgetting just how vital Hunt and Hill were to the offense last season. Hunt still played in 11 games before being released, and Hill was one of the league's most dynamic threats. It's going to be very difficult for Kansas City to replace that, which makes Watkins all the more important in finally reaching his potential.

Think about it. Who are Mahomes' other options as far as wide receivers go? You have a rookie in Mecole Hardman and a couple of young and very unproven wide outs in Demarcus Robinson and Marcus Kemp.

Gone is Chris Conley, who headed over to the Jacksonville Jaguars.

So, really, Watkins is the only reliable target that Mahomes has outside of Kelce, and that can mean one of two things.

Either Watkins will have the type of season he did back in 2015 (if not better) and the Chiefs will once again have a top-flight offense and be able to contend for a Super Bowl, or Watkins will continue to wallow in mediocrity and Kansas City's offense will be significantly stunted as a result.

Let's face it, the Chiefs don't exactly rely on their defense for wins. It's all about Mahomes and the offense, and if Watkins isn't able to step in and at least adequately fill the shoes of Hill, Kansas City will be in some trouble.

Watkins does not need to be Tyreek Hill. He just needs to be the best version of himself, and hopefully for the Chiefs' sake, Mahomes can help bring that out of him.
