I believe they'd rather lose than consider rogue/suspect characters to fortify the team. Okay, they'll consider suspect characters if it's the right kind of character issues: flakiness, insubordination, childishness, mental health troubles.
If people think championship teams are top to bottom nothing other than great human beings, think again. Serial womanizers, individuals with tumultuous home lives, petty criminal behaviour, bigots, misogynists, drug addicts, alcoholics, gun enthusiasts have populated and will continue to populate the roster of championship teams. This is because sports are results based not virtue based.
Sounds like it was a perfect situation to exploit for a team looking to make an impactful short term addition to its lineup at a low cost.
