Landing legs, even in their folded position, will give some aerodynamic resistance to roll.

That vehicle may also have landing legs. #falcon9Wont they need to do more Grasshopper flights first to get the landing system down? There is a big difference between landing in the middle of the ocean and an exact spot on land.Adding landing legs does not mean they will land it on land - they might just add them to test the shape of the stage, the diffirent center of gravity. I doubt they'll do full boostback - need to build a landing area for that first anyway.So, same flight as today, just with added legs / leg deployment just above the ocean is a possibility.

Jeff Foust @jeff_foust nowMusk: did recover video of the first stage reentry, hope to post it online later this week. #falcon9
Jeff Foust @jeff_foust 14sMusk: goal is to attempt 1st stage recovery on all future CRS launches and many others; next two (w/out recovery) more of an anomaly.
