Which Rookie RB should i pick up??

Deroit has a lot of RBs..

Dobbins will be the man NEXT YEAR;

Get MOSS ASAP..If you haven't yet.

Zack moss if you haven’t drafted yet 

I need more info.

Swift if it's a full PPR league, followed by Moss, and then Dobbins. 

If it's a dynasty, give me Dobbins 1st. He's built for that team.As for Swift, if Matt Patricia doesn't win, he will probably be gone. Who replaces him?Moss is solid with best lead runner on the team, but in a good position.Remember, rookies are more under prepared than EVER before. You need to be patient.Good luck.

Try to pick up Derrick Henry he is quite effective!!!

Your QB doesn't matter. Take Swift of those.

All three are very promising. I can see Dobbins having equal playing time as Ingram.

None of those players knows or cares who your fantasy team QB is.  It won't affect their performance.

Who I'd pick up might depend on the rest of your RBs.  Dobbins might be best, but it might take a while for enough people to realize he's better than Ingram.  Swift will do more sooner.

whichever one you want to pick up
