"Now that I think about it, Tyler did a lot of game moves, he really did. And if I was up against JC, I feel like I would have still won, like, I had a good chance just because I know a lot of people didn't like that he was kind of just back and forth, and shady and all this stuff."
Kaycee added, "So, I don't know, it would've probably still been pretty close, but overall I feel like I would've come through to win."
The 30-year-old pro football player's fate in the game was placed in her own hands when she won the final Head of Household competition of the summer and opted to take Tyler to the Final 2 with her instead of JC, whom many fans argue would have been the easier player to beat out of the two guys.
JC therefore finished the game in third place.
"I [evicted] JC just because I was super loyal to Tyler. We clicked from the very beginning. Day 1 we made a Final 2. And I was not going to go against that. There was no way I was going to unless I'd seen that he was doing something shady toward me. And he never did," Kaycee explained of her risky decision.
"We had each other's backs, 100 percent. Now I love JC, I really do. I mean LGBT representing. But I had to stay loyal... I was sticking to my word. There was nothing that was going to steer me away and it worked out just perfect."
Kaycee won the $500,000 grand prize, however, the jury was split 5-4. Kaycee told EW that she had never anticipated the jury vote would be that close against Tyler.
But while Kaycee won the most competitions this summer and played an incredible physical game, Tyler was making many strategic moves behind the scenes and always appeared to be one step ahead. The South Carolina lifeguard had also made Final 2 deals with multiple players in the game to avoid becoming a target for them.
As for whether Kaycee would be up for playing a future season of Big Brother, she's surprisingly not so sure.
"That's so hard to say right now. Just coming out of the house after 99 days, as of right now, I don't know. Maybe [after a] little break... I've been watching this show for years, since the very beginning, and to actually be in the house is a whole other level," Kaycee told EW.
"No one will ever know how it feels to play this game or be in this house unless you are in there. It is crazy and very mind blowing and I did not expect it to be this hard, you know, and it's a lot easier watching it that's for sure. I appreciate the experience and being able to play this."
