The Titans signed Brandon Weeden when Mariota got hurt and didn't even give Kaepernick a tryout. Collusion or not, there is zero football justification for that.
You have no idea what money was involved so you can't judge the decision making process.
At least in a court case, those details will be made public and we'll have a better idea.
And if their intent was to tank for a possible franchise QB next year......
But for the record, I do believe there was some collusion but don't believe they'll be able to prove it.
The question will be whether the league thinks it's worth the possible bad press and decide it's in their best interest to settle.
