2000 yards on the ground? That would take over 400 carries by DD - not going to happen.
2000 yards combined rushing & receiving? It's possible, though I expect Hollings to get some of that action. I'm thinking DD gets about 275 carries for about 1250 yards with Hollings getting maybe 120 carries for about 600 yards. Not quite 2000 between them, but still formidable.
