N is a possibility. The concept of a winterizer is that applying 1#/k of a fast release N source after the turf has stopped growing at the end of the season will result in early Spring green-up. Seeding and applying starter fertilizer early enough in the Fall for the seed to germinate would be prior to the established turf's growth stoppage. The timing of the N app would have been too early for a winterizer and its resultant advantages. In addition, the Lesco app rate would have only applied 3/4# of N. In opposition, many/most lawn services have now adopted applying a winterizer. Also as GrassDaddy mentioned, most services also apply a preM with N and although it's a bit early, they may have already done that to the lawns in your neighborhood. It's way too early for pre-m in Ohio, but I saw a service doing it last week.
Either one of those situations could create the difference you are seeing.
