Unlike the MD-90s there's a big fleet of in-service 757s across a large number of operating carriers. FedEx will fly them 'til the end; they are presently the largest 757-200 operator. FedEx is still flying modified DC-10s from 1971 and 1972.
Not really that important to your point - but unless something has recently changed, isn't FedEx is the second largest operator of 752s just behind Delta (by a few.. obviously Delta has way more 757s overall if you include the 753 variant).
