Driver by Number: Nos. 91-09 revealed this week

Editor's note: On Tuesday, we'll showcase the best and most iconic drivers from Nos. 91-09 in the final week of our Driver by Number project. The selection of the No. 99 will be unveiled Monday at 6 p.m. ET exclusively on "NASCAR Race Hub" on FS1. Who wore it best? As it applies to NASCAR, that age-old question might refer to fire suits, driving gloves or helmets. This summer, NASCAR.com is taking a different tack -- with car numbers. Our Driver by Number project will ask: Which driver either had the most success or was most emblematic with the closest association to every car number ever run in NASCAR's top division. MORE: All Driver by Number content We'll be counting up all summer long with weekly Tuesday morning reveals and features, from Nos. 1 to 99 and all the aughts (No. 0, 00, 01 … ) taken 10 at a time. Check in every Tuesday to see who made our Driver by Number list, determined by statistical analysis and research from our archives. Then feel free to chime in with your picks and join the time-worn debate of who wore each car number the best.
