Bedard: Have Sony Michel, Damien Harris been put on notice with Patriots’ signing of Lamar Miller?

The Patriots are signing former Dolphins and Texans running back Lamar Miller to a one-year contract, a source confirmed.

The move, which was first reported by Adam Schefter, adds Miller to a thinned-out backfield with Sony Michel on PUP (foot) and Brandon Bolden on the Covid-19 opt-out list.

Miller is attempting to come back after tearing his ACL in the Texan's third preseason game on Aug. 24. He was selected to the Pro Bowl in his last full season, when he rushed for 973 yards (4.6 average) in 14 games. He ran for over 1,000 yards in 2014 and '16. He's averaged at least two receptions per game in four of his seven seasons.

Miller, 29, was one of the league's top two-way backs — behind a bad offensive line in Houston — for much of his career. He's also an excellent pass protector, and should have an easy transition into the Patriots' system after Miller's time with Bill O'Brien.

This feels like many other Patriots reclamation projects, though most have come at receiver, where a host of veterans (some attempting to come back from injuries) failed to work out, including Demaryius Thomas, Eric Decker and Cam Meredith. No harm and no foul on minimum deals, as long as you're not passing up someone who could actually contribute.

But is this move just about depth? Or could there be another reason?
