The Miami Dolphins made an interesting addition to their roster Friday in former Los Angeles Rams safety T.J. McDonald. The 26-year-old is entering the prime of his career but didn’t get any huge offers due to a pending eight-game suspension for violating the NFL's substance-abuse policy. He signed a one-year contract with Miami.

McDonald said Friday that off-the-field mistake “will never happen again." But what about McDonald’s skills on the field?

ESPN Rams reporter Alden Gonzalez covered McDonald last season and provided a breakdown:

"T.J. McDonald, listed at 6-foot-2 and 217 pounds, is a hard-hitting safety who was ideal for the aggressive style of former Rams defensive coordinator Gregg Williams. Last season he also made some pretty drastic improvements in coverage. Pro Football Focus had him with an opponents’ QB rating of 68.8 while serving as the primary coverage defender, which was nearly half the QB rating he surrendered over the course of his first three seasons (121.6). McDonald played in every game last year and registered six defended passes. At 26, he was also a young free agent. He should provide the Dolphins with a major lift in their secondary for the second half."

McDonald will be a non-factor for Miami until at least November due to his suspension. However, the Dolphins need safety depth and his return late in the season will be a boost.

Miami, which won 10 games last season, believes it will be a playoff team once again in 2017, meaning McDonald could contribute in meaningful games down the stretch.
