Well, given Croft is playing more as a batsmen and 4th seamer, they are apples and oranges really. We've seen in the past having Hogg at 6 is a mistake and if he was 4th seamer he do SFA. Hogg is battling Cork for a place, and he should be in ahead of him at the moment imo, Hogg has been in great form so far this year, Cork is past it, but the selectors have Hogg pinned down as a OD player, not without reason.
Smith is fit at the moment, but it was between him and Newby for a spot, they both played in the Seconds last week, Newby to 5-22 and 2-23, Smith did nothing. I'd have Smith in ahead of Saj, that's not giong to happen though so i don't have a problem with Newby's selection ahead of him for this game.
