It's best to have honed your talent so as to make fewer and fewer as you ascend toward larger markets. I listened, all my life, to sportscasters. As my interest in the profession sharpened, I listened more critically. It doesn't pay to totally copy someone's style, but being a good listener, you can generally pick up a healthy set of do's and don'ts. If you hear or see something that fits your style, employ it.
Radio is a true test of a sportscasters talent.
And that's about it. If you think sportscasting might be your thing, I wish you luck. May it be as richly rewarding for you as it has been for me. 1999 American Sportscasters Association, Inc.
