RBs - This one really depends on their health, and I say that because health has been somewhat of a concern with these guys. If Murray and Jones can stay healthy for most of the season, then I'll say stock up...way up, but if the group suffers more nagging or season ending injuries, then it's going to be another year like last year. As for FB, well, from what I've heard, Vickers is the guy...a blocking machine, so there you go.
So I'm going stock up...keeping the positive health vibes out there.
WRs - Same health issue here, really, but mostly due to Austin. I think Bryant is going to have a gigantic year (draft him early in fantasy, people) and not miss much, if any, time. Miles, though...we'll see. But if he stays healthy too, again, the stock on this group is going to be WAY, WAY up. I know we lost Robinson, but let's be real here. If Austin and Bryant are healthy all year, I doubt you're going to miss Robinson, and I think Coale, when he gets healthy, is going to surprise some people.
Not sure if we're counting TEs here, but if so, Witten brings the average up by default. When is the last time he missed playing time with an injury? When was the last time he had an off year? Answer: he doesn't have off years.
I'm predicting stock up with these guys.
