After leaving Southern Mississippi in 2006, Johnson spent time in training camp with the Colts, then had various stints in NFL Europa, the AFL and the CFL before finding a home with the Saints.
Since Johnson went undrafted out of college, the Saints would not receive any draft pick compensation were they to place the lowest right of first refusal tender on him. But they would reserve to right to match any offer sheet he was offered.
The 2013 RFA original round and right of first refusal tenders amounted $1.32MM. With the 2014 salary cap projected to increase by $7MM, or 5%, one would expect a similar bump with the tenders.
