Um, a High Ankle Sprain is not an excuse. That's a legitimate injury. I think so far this year both players have looked good. I don't see what you're seeing about Lindsay being a better interior back, though. The guy is an arm tackle waiting to happen. He's better in space because he couldn't break a tackle if his life depended on it, but he can certainly make people miss if he's got the room. Royce did the opposite of what you claim he does when he scored that TD. He looked the bit of a power back.
This will continue to be a frustrating situation for owners of both backs, but should one get hurt, the volume will prop up the remaining player. Between the two of them, they are on a 16 game pace of 391 carries and 133 targets. In PPR, they are RB18 and RB24 in points per game despite the split. This is not a good offense, so I think those rankings are as good as anyone should have hoped for if they were being realistic.
94 was about to tackle him until his offensive lineman (66) literally picked him up, took him from 94, and body slammed him into the end zone. Hilarious you think that somehow helps his case as a tackle breaker.
