  In this note, we discuss the impact of the recent Belle result on the various
theoretical explanations of the $R_D$ and $R_{D^*}$ anomalies. The pure tensor
explanation, which was strongly disfavoured by the measurements of $F_L^{D^*}$
and high-$p_T$ $p \, p \to \tau \, \nu$ searches before Moriond, is now
completely allowed because of reduction of the experimental world-average.
Moreover, the pure right-chiral vector solution (involving right-chiral
neutrinos) has now moved into the $2\sigma$ allowed range of the LHC $p \, p
\to \tau \, \nu$ searches. We also critically re-examine the bound on
$\mathcal{B}(B_c^- \to \tau^- \bar{\nu}_\tau)$ from LEP data and show that the
bound is considerably weaker than the number $10\%$ often used in the recent
literature.
