There’s no clear cut answer to this, because of Dalvin’s injury history.
It’s REALLY tempting, because if you do it and he stays healthy, you won’t see much of a dropoff at RB and you’ll also become absolutely fierce at WR.
But we all know Dalvin’s a roll of the dice healthwise. There’s also talk that while he will get goal line work, he will not be a 3 down back.
Anyone telling you that the answer to this is obvious can’t admit that we just don’t know what will happen.
I personally would do it because of what it does for you at WR and because it potentially yields a higher reward than your present situation. Plus, if Dalvin does go kaput, you’re still in pretty good shape with Jacobs, and potentially Jackson (the Gordon holdout looks like it was built to last).
But this decision is yours and yours alone.
