I think Donga intended to fight since they discussed making weight in their interview, but decided to back out in the end out of fear.
Just off the top of my head, here are some times outside the past week when based on Tonka and co's actions I thought "Yeah, Tonka's ducking this fight"
-Failure messaged Andy and tried to gaslight him about the contract being unfair right after it got announced
-Tonka tried to claim that Andy showing himself holding the contract on stream was violating the NDA
-Tonka refused to submit a picture of himself as stipulated by the contract
-Tonka refusing to show himself signing the contract on social media because he "didn't have social media," which I guess excludes YouTube
-Tonka telling his audience to not bother coming
-Tonka using Andy's offer to fight him in the streets of Jacksonville to say that Andy wanted to duck the official fight
-Tonka refusing to hype up the fight at all
-Tonka constant saying baseless "rumors" like "Andy's not coming" or "Andy hasn't bought a plane ticket"
Let's be honest, he never thought that Tara LaRosa would call his bluff and set it up, and he never thought that Andy would take it seriously. And the past two months have been him squirming trying to find a way to bait Andy into backing out
