49ers guard Jon Feliciano gets into nasty social media arguments after Super Bowl loss

After the San Francisco 49ers' devastating loss to the Kansas City Chiefs in Super Bowl 58, several people started pointing fingers trying to determine who was to blame for the defeat. Many pointed at Kyle Shanahan, as some players didn't realize that having the ball second in overtime would've been an advantage. Many others blamed rookie kicker Jake Moody for having an extra point blocked, despite him making two 50-plus yard field goals earlier in the game.

Well, based on a tweet from 49ers O-lineman Jon Feliciano, Feliciano believes his teammate and fellow offensive lineman Spencer Burford is to blame for San Francisco not getting a first down while they were in the redzone.

Feliciano tweet and fallout explained

Feliciano responded to a tweet blaming right tackle Colton McKivitz for not blocking Chris Jones on a pivotal third down in overtime. Feliciano claimed that Jones was not McKivitz's man to block.

This obviously created another question. Who was supposed to block Jones?

Feliciano responds, never naming whose job it was but hinting that the play would have been fine if the person in question did what they were supposed to.

Well, after that, the player in question reveals himself. It was none other than guard Spencer Burford.

To Feliciano's credit, he immediately realizes his mistake and tries to take back what he said, blaming his rashness on being hungover.

At this point, people didn't know who to be upset at. Feliciano seemed genuine in his apology, and you can't blame him for being upset after enduring the biggest loss of his career. He even went out of his way to not name anyone specific. He was merely defending McKivitz. At the same time though, based on what Feliciano said, anyone could realize that if blocking Jones was not McKivitz's job, it was whoever was next to McKivitz. There really was only one option.

At the very least though, Feliciano seemed to realize his mistake and backed off. However, that was just the beginning.

In comes Eagles lineman Jalen Carter

After these tweets, Philadelphia Eagles' rookie defensive lineman had some words of his own, expressing dismay with Feliciano via a story on Instagram.

According to Carter, during the Eagles' Week 13 game against the 49ers, he and Feliciano got into a heated argument where Feliciano mentioned the car accident that Carter got into in college that ended up killing his teammate Devin Willock as well as Georgia team staffer Chandler LeCroy.

This is obviously a super low blow if true. No one deserves to have the death of their friends hung over them like that. Feliciano, however, defended himself, claiming that Carter was the one who started the inappropriate comments.

Obviously, it's impossible to tell who's being truthful here. If Feliciano is telling the truth, then Carter is absolutely in the wrong. Feliciano may not have responded appropriately, but you can't blame someone who just had their family's lives threatened.

Feliciano finished the conversation up once again expressing regret for how he handled the situation with Burford, but doubled down on his argument with Carter.

Feliciano basically states that Carter wanted to talk trash, but couldn't take it when the same energy was tossed back at him. He also stated that he has too much to live for to give Carter another thought.

As stated earlier, it's impossible to tell who is in the right in this situation, because we don't know the truth of what was said. Regardless though, that moment happened months ago at this point. Feliciano seems genuinely sorry for throwing his teammate under the bus, and that's the only thing we can see through these social media posts.
