If more than one doublet of composite Higgs bosons is formed with quarks and antiquarks alone in the Nambu--Jona-Lasinio model, their couplings to quarks are subject to interesting constraints. The Higgs doublets orthogonal to the linear combination responsible for mass generation almost decouple with the right-handed {ital t} quark, but couple with one or more of the right-handed {ital u}, {ital d}, {ital s}, {ital c}, and {ital b} quarks with Yukawa coupling constants of order 1. If there are only two light doublets, the doublet orthogonal to the mass-generating combination is likely to couple with the right-handed {ital b} quark with a Yukawa coupling constant {congruent}{ital m}{sub {ital t}}/{ital v}.
