IMO Hendy was drafted to give the Rams a back who can come in for Gurley without changes needing to be made to the play calling. He's a plus athlete (not a TG talent but few are), thrives when he's got a seam, has the speed to flip the field, good balance at contact, and knows when to get small and take what he can.
I guess I just don't get the concerns with him. The guy isn't gonna be Todd Gurley in his prime. But he did show us good hands and speed on the edge in a small sample size. He did get what he could when the blocking was subpar, and what I really liked was he didn't dance around when lanes weren't there which is what some backs do transitioning to the NFL. How many teams have guys who can flip the field on their depth chart? That's what he is IMO.
I'd like to see the Rams replace Brown with a physical type but that's just me. Still, that doesn't affect my take on Hendy.
Some vids from last season to remind folks this kid should be a guy we're excited about in year 2:
