Cam Skattebo still top option in crowded Giants backfield

EAST RUTHERFORD, N.J. -- The New York Giants' running back room got a bit more crowded this week with the signing of Najee Harris. He is a four-time 1,000-yard rusher looking to prove once again that he's a high-level back.

Harris took three days to get into live drills. He received three carries during joint practices Thursday with the Miami Dolphins.

But Harris isn't joining the Giants to be the fourth option behind Cam Skattebo, Tyrone Tracy Jr. and Devin Singletary. He was brought in under the premise that he's going to be a significant contributor, even though a source told ESPN he signed a one-year minimum salary $1.215 million deal with no guaranteed money.

Harbaugh and the Giants seem ready to let it play out.
