Got to remember, BHBH works differently from the law firms you see on TV, and it seems how they work somewhat in real life.
You go to a law firm, they assign a lawyer to you, and that dude and a paralegal pretty much deal with your case for you. They may ask other lawyers for help and assistance for ideas-bouncing, but generally you get your lawyer type and he deals with the stuff himself as his assigned case.
You go to BHBH and you're basically hiring the entire fucking firm. Sure, you got a lead on the case but the entire firm pitches in on various meetings, considerations and random white boards which can be scribbled on by any member of the firm. They no doubt hold war councils where all their lawyers sit in and discuss what the best strategy is.
This means, in terms of simple experience in years, you're hiring 100+ years of experience versus the MoRon's combined 30.
EDIT: Should also chip in, that Ty is impressed by Nick's ability to predict. He's coming up with similar, solid strategies they've no doubt considered at their war councils. Meaning Podunk Lawyer in the middle of nowhere, Minnesota is on the same level as a room full of ruthless lawyers and a dude from MENSA.
