I think Achane and Chase Brown is the right call. You're not really getting any value on JT in the 3rd, versus 4-5 rounds of value on Chase Brown and 6-7 rounds of value on Achane. He must be a hold over from drafting him his rookie year?
With those two locked in together in 7&8, you can focus on getting 2 WRs in the first two rounds, you can target Daniels in the third if you want him back, Kittle in the 4th if he's not a keeper, and then go for a young rookie RB as your #3 - sometimes Henderson will fall here, but almost always Harvey and Kaleb, and then a young upside receiver, Jameson Williams / Pickens / Tet / Hunter, in e 6th.
Obviously other teams keepers affect who is available in the draft, but this would be my approach going in.
