His potential market value: Decent. Delmas would have a much higher value if not for his knees, which will be a concern for any team that does choose to sign him. He was limited to one practice a week because of his ailing knees and the condition doesn't appear to be one that will magically become better over time considering he plays football. But he was available for every game, which was a major factor in him becoming potentially a priority free agent for teams. There appears to at least be some interest in him since he has visited with clubs since being released by Detroit last month.
However, Delmas is known for being more of a risk-taker than Clemons in coverage. In Detroit, Delmas allowed 313 yards and four touchdowns in coverage this past season. By comparison, Clemons only conceded 127 yards and two touchdowns. Although the two had different roles on different defenses, Clemons is thought to be more reliable in center field. Still, the drop off in coverage isn’t significant enough to scare the Dolphins away, especially considering Delmas would likely compensate by producing more interceptions than Clemons. As a more capable defender in run support, Delmas could also be more of an interchangeable safety with Jones.
If the argument was purely a matter of on-field performance, Delmas would be a solid addition to Miami’s secondary. There’s no guarantee that he would emerge as an upgrade over Clemons, but he possesses the potential to become just that.
