I think the injury to Calais will force the Rams to sign a waiver wire RB simply for the last game. Or they will go into it with Anderson and hope he can carry the entire load. The Rams cannot afford another RB injury so Funk and Jones definitely won't play. If they are smart they will sign a FB who can remain on the roster and give the others the lead blocker they need.
McVay gets blinders on and simply doesn't see the obvious at times. He wants to run a power run attack but has no lead blocker. TE blocking is different than a FB. TE's simply impede while a FB plays with power and will blow a LB out of the A gap. He's also, unaccounted for in many passing defenses in play action so you need a guy with power, at least 4.7 speed and hands to catch. They don't have to scan the wire they can also sign an UDFA FB. The Rams are set at RB 1-3 what they need is a FB as their #4 RB.
DeCamillis made a huge mistake is releasing Webster. He's looked good with the Niners.
BTW Nick Scott with his 4.43 speed was a RB before converting to DB. He also returned kicks. At 5'11" 200 lbs he's not a small man. His 40 times have been as low as the 4.3 range, so he definitely fits their RB profile. They are deep at safety, they can use these last couple of weeks to coach up Scott as an emergency RB/KR if they don't want to sign one off the street. This would be especially true if Calais would be expected back by their week 11 bye in mid November.
