The San Diego Chargers WRs were just a smidgen below phenomenal last season. Malcom Floyd and Eddie Royal had career years, and it would not be unreasonable to expect Keenan Allen to bounce back in 2015 after a "sophomore slump". So, should the team have any interest in Jacoby Jones?
In a word(s), probably not. Jones was a very efficient and effective deep-threat with the Houston Texans, playing the Malcom Floyd role to Andre Johnson's Keenan Allen. However, since moving on to the Ravens, Jones has mostly been used as a kick returner, punt returner, and slot receiver, and hasn't been much more than "average" in that capacity.
The upside to signing Jones is that it would give the team some backup options at KR, PR, and a backup plan for both Royal and Floyd. However, there's a good chance that Jones is going to get better offers from other NFL teams where he won't need to accept a role as the 4th WR on the Chargers.
That's what I think. What do you think?
