Let me just say, I agree with you to a degree. If we were a rebuilding team that went 3-13 instead of 13-3 then I would definitely say RB in round 1 is really stupid. Like the Giants did with Barkley which clearly didn't make sense when they needed a QB. But our offense literally needs a game breaking RB and a good TE from being fully dominant. It's almost there already.
We have drafted RBs in the 3rd round each of the last two years and how has that worked out? Zach Moss, I'm not necessarily giving up hope that he can be a really good player yet but I'm pretty sure we know what we have in Singletary at this point. And neither guy is really a guy that can change a game or has game breaking speed.
To me, there is a clear difference between the RBs you draft in Round 1 as opposed to after. Tomlinson, AP, Elliot, McCaffery, Barkley, Gurley, Barry Sanders, Emmitt, Marshall Faulk. Those guys are or were difference makers for their teams. You can get guys in other rounds like Gore, Kamara, Aaron Jones, LeSean McCoy, Terrell Davis, Thurman and maybe even luck out on an undrafted guy like Fred Jackson or James Robinson and some others but I feel like the odds of that are a little slimmer. We are in our SB window. There's no point in not taking a difference maker at position of need that can make us even more dynamic because "RBs are a dime a dozen" or a "non sensical 1st round pick". I personally would like a pass rusher with the first pick but have no issue at all with Etienne or Harris at 30 if either player is there. I just don't see the point of drafting another 3rd Round RB that's basically the same as what we already have
