The preseason for the Carolina Panthers finally came to an end on Thursday night with a 19-10 loss at home to the Pittsburgh Steelers. While it’s not cause for panic just yet, the Panthers did not look sharp at all this month, posting an 0-3 record and managing just two touchdowns. By Tuesday afternoon the Panthers have to trim their roster from 90 players down to 53. The worst performer for Carolina during the preseason was third-string quarterback Jack Plummer, who posted a team-low 35.1 overall grade from Pro Football Focus.
