Electronic energy bands of metallic ${\mathrm{TiTe}}_2$ are calculated, and the transport masses (n/m${)}_{\mathrm{\alpha }\mathrm{\beta }}$ are evaluated. Comparison with the measured resistivity shows that this is an ordinary metal with a moderate electron-phonon interaction in the usual quasiparticle gas description. However, photoemission line shapes as measured by Claessen et al. are not consistent with this picture, and are used to predict a resistivity that disagrees with experiment. Similarities to high-${\mathit{T}}_{\mathit{c}}$ superconductors are pointed out. Possible resolutions are discussed.
