Dolphins sign Mark Walton

Xavien Howard may believe he cashed in big time with his new extension with the Dolphins, but Mike Florio explains why the cornerback may end up regretting the deal he signed in the coming years.

Running back Mark Walton is getting his second chance.

The Dolphins have signed running back Mark Walton after a weekend tryout at the team’s rookie minicamp.

A fourth-round pick in 2018, the Bengals cut Walton earlier this year after a trio of arrests.

The Dolphins also signed center Kirk Barron and cornerback Jamar Summers. The Dolphins waived/injured center Connor Hilland and safety Rob Rolle.

The Dolphins brought Walton to the rookie minicamp for a look-see. On Saturday, coach Brian Flores explained that “think[s] people deserve a second chance.” Beyond the fact that giving an NFL player a second chance takes away another NFL player’s first chance, the reality is that the only guys who get second chances are those deemed to be talented enough to warrant one.
