Yes, the legacies hire primarily from military, and regional 121 operations, but there are pilots being hired from the fractionals as well. Many pilots at the fractional's aren't even looking to go 121 especially if you are a Captain at Netjets, many of whom are making well north of $200k. Had a friend recently hired with a legacy and he didn't have 1 hour of 121 time, he did however have a few thousand turbine pic, which could be hard to come by at Netjets if you don't have pic time.

With the upcoming hiring wave approaching and the demand for pilots by the Legacies, and LCCs, as they exhaust supply from the regionals, I could definitely see them hiring more fractional pilots. Different subject, the Legacies rely so heavily on their regional feed, (I believe 50% of US domestic departure's are from regional feed) how will they keep the regionals alive as it is clear they need the lift they provide from smaller markets?
