SportsDay's Jon Machota answered questions in a chat Friday. Here are some highlights.
Question: Derrick Henry seems deceptively fast once he gets in the open field and is obviously powerful. But does he have that great burst and acceleration that makes a home run-hitting NFL back?
Jon Machota: Henry has speed but his size and physical nature are what allowed him to be so successful at Alabama. I don't know if that same style will work as well against NFL players. It might. If the Cowboys feel it will, he could be a second-round option.
