Yes. They both have Get further forward. I think they have enough for space for it. At least with my more defensive FBs and CFs instead of DLFs, I think there's enough space to have them roam around far up the pitch.
They actually get almost as many crosses as my FBs (about 75-80% the amount) and with a better completion rate. And I think part of that is that they are ready to get up field fast. Don't know though. That might just be theory. But it makes sense to me.
Sounds like a good idea though. For versatility. I'm just a sucker for symmetry. Whenever I have 2 players in the same role I try to give them the same PIs. Otherwise I just keep second guessing myself regarding whether the player performing better is doing so because he's just better, or because of the instructions. And if it's the instructions, shouldn't they both have them then? Hehe.
