Everything's a gamble in some form. What if you take Haskshaw, denying you the opportunity to try new flankers, but they don't make 2019 in good enough form and you don't have replacements?
There are something like 27 games left between now and Japan. I absolutely agree that we need to start blooding successors for the likes of Robshaw and Haskell now, but everything we've seen from Eddie so far suggests that it will be a gradual process rather than an immediate handover.
For Argentina and the AIs, I'd have Robshaw and Haskell at 6 and 7 with Sam Jones and Sam Underhill replacing them in the 2nd half.
I also think we need to think carefully about how long a player gets before we make a call on whether they are good enough to keep around or whether we swiftly move on.
For example, how much longer does Hughes get before we say he's not a test 8? He's had plenty of game time now and I think it's more than fair to say he's yet to convince ... Assuming Eddie sticks with him and he's equally mediocre against Scotland and Ireland, I think we need to look at an alternative for the Argentina tour.
I don't want us to fall in to the trap of expecting too much too soon and giving lots of players 4 or 5 games, but there does need to be a point where we make a judgement call and Hughes must be getting close to that.

FWIW ... my 32 man squad for Argentina would look something like:
1. Marler / Genge
2. Taylor / Cowan-Dickie
3. Sinckler / Hill
4. Attwood / Barrow
5. Lawes / Ewels / Beaumont
6. Robshaw / Jones
7. Haskell (c) / Underhill / Evans*
8. Clifford / Fearns
9. Robson / Spencer
10. Ford / Lozowski
11. May / Addison*
12. Slade / Te'o
13. Marchant / Tompkins
14. Rokoduguni / Yarde
15. Woodward / Haley
I'd give The Brand the chance to captain the side.
Evans and Addison injury dependent and possibly a bit generous on Beaumont.
