tbf to Hill he's at least had a few good performances for England - I still wouldn't pick him though (he obviously wants to go to France and it's just the injury that's kept him here because his contract got cancelled - he also went off injured this week so probably won't be available), and would be more inclined to give some actual development time to Isiekwe
I know i'm a bit of a broken record with him, and he's not exactly backed me up with his England performances so far, but he's so good for Saracens, especially in the defensive lineout, that I do think he's worth getting some consistent game time rather than the 10mins here and there he's been getting to see if he can actually hang at the international level - his last start was 4 years ago
Though the time to do that was when Martin and/or Chessum have been out injured, really
