Honestly, upon reflection Walker and Gausman kind of just slide in with Shoemaker, Anderson, and Thornton as inconsistent or unreliable rotation filler with some upside. Gausman is slightly better than the other names and both Walker and Gausman probably have more ultimate upside than the other three, but that would be a rotation with zero #1 or #2 starters, arguably no #3 starters, no horses, and everybody liable to either put up an ERA over 5.00 or barely pitch.
If Gausman is part of the solution then I think that solution also needs to include a better and more reliable pitcher in front of him. Keuchel, Ryu, Wheeler. Pineda doesn't fit that bill for me even though I like him as a target. A one year veteran like Hamels could fit the role.
I mean I'll take anything, don't get me wrong. If Gausman and Wade Miley is all the front office can pull off, then that's an improvement I guess but I don't think it would exactly accomplish what the team should have a mind to accomplish this offseason.
I assume Gausman just wants a one year deal. If Walker needs to rehab for half of the season and will sign a two year deal then that's a different thing altogether.
