Abstract	We explore aspects of the phase structure of SU(2) and SU(3) lattice gauge theories at strong coupling with many flavors N_f of Wilson fermions in the fundamental representation. The pseudoscalar meson mass as a function of hopping parameter is observed to deviate from the expected analytic dependence, at least for sufficiently large N_f. Implications of this effect are discussed, including the relevance to recent searches for an infrared fixed point.
