Richardson had a very good year as a run stuffer. His pass rush leaves much to be desired, IMO. Lotulelei was a main reason for Carolina's strong defense but just doesn't get the stats or flash that people look for in DROY.
Kiko was good in run defense (save a few plays late in the year), excellent in pass coverage, signal caller from day 1, AND played every single defensive snap of the season. Impressive to say the least. I think the length of the NFL season weighed on him towards the end. He looked much slimmer than the beginning of the year. I'm sure he'll bulk up in the off season and be ready for the long haul next year.
