Id say Colon will be a marginally effective LRA with a pull rating of 4 or even 5. The 59 vs right combined with the measly velocity of 52 means he will be throwing a lot of pitches between outs, and many of them will be ineffective. If his velocity was 99 Id have no problem having him start games and with a pull of 3.
As for Estraella his 52 vs R is obviously terrible, but his vel is awesome, and his 2-5 pitches are great. I think he could be a 5th starter with a high pull of 4 maybe even 5. If his 1st pitch was elite like 97+ Id give him the 3rd starter position with a pull of 3-4 though.
