Carefully choose citations. The judge must decide which cases to read. Help with this decision. Tell the judge exactly which cases to read. The judge is not going to read seventy-five cases, and you should not expect him to.
If the law is “well settled,” use the version that either squarely meets the facts of your case, was written by the Supreme Court, or was most recent. You do not have to go back to Brown v. Credit Card Center on every summary judgment appeal.
Do not worry about not including “enough” citations. No points are awarded to the party who cites the most cases. The question to ask is whether this case adds something substantive to the brief.
