I'm not really sure that lends much credence to that other than McDonnell knowing Flores and knowing he'd be in the mix. Especially because if he's the top choice, he shouldn't really have to "come win the fucking job" to begin with. It'd be his to lose.
That said, the bigger issue is the latter in which they're only bringing candidates in to fill a quota. Daboll is a fine hire and makes a lot of sense since they just hired a guy from the same organization to be the GM. It's pretty bad to let it leak outside the organization that you already found your guy when you still have guys to interview, it's even worse when you're bringing in minority candidates because you need to meet a certain quota. Based on the experience he had with the Broncos interview in 2019, I do not blame him Flores for just being tired of this shit.
