I think the RFA Right of First Refusal tag for CRod is 3.5M and I would pay that immediately. Bill is also only getting 1M in salary. 4.5M for that duo is a huge steal. CRod runs really angry, I love watching that.
Personally I want to see what Bill can do this year. Lots of RBs need that first year to adjust to the speed of the NFL and then they figure it out. I don't know his ceiling, but I'm not willing to write him off. But if the FO thinks he isn't and can't be "the guy" then fire away on some bigger names.
If we sign Walker, he both pushes Bill down and makes drafting Love really infeasible. The #7 pick is getting 8.9M/year AAV, and Walker, I gotta think he's gonna push for something like 14-15M and at least a 3 year deal, and he of course should, this is probably his one big chance to cash in. Between those two we'd suddenly be at 24Mish for two RBs, that's not really workable imo, and you can't really give them the carries they deserve either, just not gonna be enough carries to go around.
In my mind, it's either Walker or Love, but I don't think you need either to have a good backfield.
I'd grab White/Gainwell, and roll with Bill, CRod, and White/Gainwell, and then if we end up with Love we aren't in as much of a multi-car pile-up.
