I agree. Age and projection of future useful years is the first concern.
Yamamoto (25) Major risk, yes, but at 25 years old, I'd roll the dice. (Pun intended)
Giolito (29) I like the age, but am not sure he's even a solid #2.
Ohtani (29) Out of price range and reasonability
Snell (31) 5 years but will get 6+ and is not a workhorse pitcher
Nola (31) 5 years but will get 6+ somewhere
Montgomery (31) 5-6 years. (I think he may be the guy we add.)
ERod (31) 4 years but may not want a return to BOS
Stroman (33) 3 years but will get 4-5 somewhere
Wacha (33) 3 years max
Gray (34) 4 years, and I'm not so sure I give a 34 year old 5 years. (I like him, though.)
Kershaw (36) 2 year deal, but it will be hard to pry from LA
Cobb (36) 1 year with an option, but I hope we do better.
Lynn (37) 1 year, but I don't see him as a guy I'd want.
Morton (40) 1 year deal
Others...
28 Flaherty- age makes him interesting
29 B Keller
30 Severino
32 Lorenzen, M Perez
33 Clevinger, Heaney
34 S Lugo, Stripling, Hendricks
35 Paxton, Maeda
36 K Gibson
37 Ryu, Carrasco
38 Cueto
40 Greinke
44 RHill
Sign one good one and then a second one like Charlie Morton, then trade for a younger pitcher. Add three.
The pen would be awesome with as many of th4ese guys in it as possible:
Paxton (likely the #5)
Crawford
Houck
Whitlock
