I'm going to be incredibly brutal with this answer. The majority was decided early on in the game, it was me, Luke and Wes being in a more powerful position in the game, and I simply could not trust you for your affiliation with the weird Taco alliance at the start of the game. You could've worked more on your social game, which was a reason why I didn't particularly trust you.
In addition, I knew that you and Daniel/Ethan were a pair and duos can be a threat, especially when it gets closer in numbers. I'm sorry that you didn't get much of a chance to play with your brother, but he hurt his game by being inactive for a significant portion of the game.
You also won a few vetos to save yourself, so you were also targeted because of your ability to be good at challenges, which might've prevented you from going home later in the game. So to summarize, you were targeted for the few connections you had, the fact that you were an outsider from early on and your ability in challenges.
