I think a lot of us probably were thinking that Claire was talking about Matt when during Luke Cage she talked to Luke about knowing a good lawyer friend who could help him with his legal troubles, and then the opening to The Defenders revealed she was actually talking about Foggy. I don't know if anyone else sometimes feels like it was a bait-and-switch on the writers' part. The way Claire talked in Luke Cage, it definitely felt like she was talking about Matt when she said she knew a good lawyer, given Claire's past association with Matt. While good points can be made for why Claire picked Foggy instead of Matt (like "Claire never saw Matt in action as a lawyer, how would she know he's a great attorney?" or "Having Foggy defend Luke sets him up to come back around to reestablishing his friendship with Matt in the next season of Daredevil"), I think that it would've been been better for the show if Matt had been Luke's lawyer, because it would've given Matt and Luke a chance to have some character bonding.
