Hartline

The brother of Dolphins receiver Brian, Hartline signed with the Colts as an undrafted free agent out of Kentucky last summer. He’ll be insurance in case the Pats find a trade partner for restricted free agent Brian Hoyer this offseason. In that scenario, Ryan Mallett would jump to No. 2 on the depth chart.

Undrafted out of Kentucky last season, Hartline was signed by the Colts, but was waived after attempting only two preseason passes. The Pats signed him to a reserve/future deal in January. He’s likely at the end of the line.
