Do i have a legitimate case?

I got pulled over sunday morning at 245 on the M pike doing 77. the thing about it is that he pulled me over with 2 other cars at the same time, and we were pulled over on an off ramp to our exit. we were all following each other and i was the middle car, now i do not know what he said he clocked the first car at, but the car behind me only had a ticket of 75. the whole ordeal seemed really dangerous and like cop tried to make the best of his fortune and pull all three of us over, but implemented a little guess work? does this sound like i have something of substance in court?
