re: Can we expect Burrow to run more frequently this season?

This keeps getting brought up - hopefully he won't be running any more. He's not super elusive, no elite speed and he doesn't mind contact. Those things can all lead to him getting hurt.
That said, 5-6 runs a game to keep the defense off balance is a good thing. Our RB talent level will be upgraded this year with 2 of the top 10 RB in the country coming in. They may take time to get up to D1 speed but we'll have better options to hand off to vs. last year.
