Miami Dolphins vs. San Francisco 49ers Prediction
I’m on the under in this one. I get the case to be made for either side here as the 49ers are heads and shoulders the better team, but we could see a bit of a sluggish performance because we don’t know how the layoff and travel from down under will affect the 49ers even with a few days off. I think this will be a bit of a slugfest and a low-scoring game, so give me the under here.
