Setelah musim pertama, MLS menderita penurunan jumlah kehadiran penonton di stadion. Kualitas liga dipertanyakan ketika tim nasional pria AS, yang sebagian besar terdiri dari pemain MLS, tersingkir di babak pertama [[Piala Dunia FIFA 1998]].
 
Liga mulai memasarkan diri pada pemain berbakat Amerika, baik veteran berpengalaman maupun bintang-bintang muda berbakat. Bintang muda timbul seperti [[DaMarcus Beasley]] dan [[Landon Donovan]] mulai tenar di MLS sebelum membobol dan bermain untuk tim nasional AS, sementara pemain mapan seperti [[Brian McBride]], [[Eddie Pope]], dan [[Clint Mathis]] terus membuktikan kualitas mereka untuk kedua klub mereka di MLS dan tim nasional AS.
