Of the 80s QBs I grew up on, I thought they all had a great throwing motion except maybe Young's was a bit funky. Marc Wilson, McMahon, Bosco were all solid. If the later QBs, Hancock, Beck, and Jake Heaps stand out as guys I enjoyed watching throw. James Lark had a nice delivery.
Too bad Munns never developed. He had a big time arm in high school. Another we never got to see was Brad Sorenson. I saw him in high school and he was smooth.
