I like this idea if Crock isn't one of the best 53. When the cold hits we will need 3 RB on roster because of Lacy's asthma; but if Croc is like #57, no doubt 4 guys will be hurt by the time winter hits.
If injuries hit in a game, as Nerd constantly reminds us😁, Cobb and Monty can cover at RB [Monty may even excel] and then Crock gets called up next week just as Steve said.
Is someone tries to raid Crock from PS, often guys can be kept by promising more $$$ or Crock will probably give them a chance to promote him.
Only down scenerio comes If Crock is raided, and then injuries hit. But, they'll be a serviceable vet out there, just look at RBs in the AFC east. Daniel Thomas, Pead, Khiry Robinson, Bilil Powell, Devlin, Donald Brown, Karlos Williams will all be cut or we can snatch good young RBs from those team's taxi squads.
If the situation is dyer like Starks and Lacy are on IR a decent back can be had for a 5th or 6th rnd pick or we could trade one of our OLBs for one. We'd probably do this even if Crock made the 53.
I dont see Rajon Neal or Alonzo Harris out there; but Dujon Harris is currently w/ SF, we could get him for a song if he's not a street FA.
Serviceable RBs are a dime a dozen and a nickel on Sundays.
