With various spin-parity assignments, the partial decay widths of $J/\\psi p$ final state are calculated. Our results show that all the $P$ wave $\\Sigma_c {\\bar D}^*$ assignments are excluded, while $S$ wave $\\Sigma_c {\\bar D}^*$ pictures for $P_c(4380)$ and $P_c(4450)$ are both allowed by present experimental data.
