Dude was the best. I didn;t have a favorite college fb team until I decided I was going to Purdue for engr.
However, as a non-cable kid, I watched the games on ABC every week, and a big draw was Mr. Jackson.
What a voice, set the table just right, and didn't overhype.
Most importantly like another long time fave that recently passed, Pat Summerall, he knew when to keep quiet and just let the moment play out. That's something missing in most broadcast teams nowadays, there's just as much of an art for when not to talk and just let the natural atmosphere marinate so the viewer can witness that.
