"Running backs have short careers more often than not and are injury prone. "
Exactly....we have been lucky to have kamara as long as we have. I think this coming season will be his decline era. And we don't have anyone else.
RB's don't have short careers. I posted it somewhere else but look at McCaffrey last year, it was year 7 or 8 and he got the 49ers to the NFC Championship Game. Barkley broke 2k in his 8th year. Henry is mauling defenses in year 9.
That's high production deep into their 2nd contract. Now go look at our first round picks and consider their play in their 2nd contract (if they even reach it). It's Lattimore, Peat and Ruiz. That's it.
