I don't think so,
Lawrence I've already explained my (guessed at) reasoning,
Hill I guess it kinda the same:
Our options at 6 are Lawes, Chessum, Isiekwe, Itoje (and maybe one of the 7s moving across, but I'd expect one of the hybrids to play there before Simmonds or Earl tbh)
I'd say his direct competition in there is Chessum and Isiekwe, as Lawes and Itoje were always gonna be there,
Chessum is in fine form for Tigers, is a genuine option at 5/6 and at a push even 8, and Borthwick knows him very well (not suggesting nepotism, just that he knows his strengths/weaknesses so it's an easier pick)
Isiekwe more of a lock than a 6 so that counts in his favour as our second row hasn't been great recently, especially at tighthead lock (where Isiekwe has been playing since going back to Saracens)
Personally I would've had him ahead of Lawes, who I don't think should be playing in this 6N after his recent concussion issues, but like with Lawrence - I can understand why he's missed out
Just unfortunate to be playing in positions where we have good depth at the moment
Edit: Actually I forgot Ludlam - I really like Ludlam but I'd pick Hill ahead of him. Can't see Ludlam starting at 7 or 8, and I prefer the pace/dynamism of Earl/Simmonds off the benci
