I think you can play Steindl or Blanchfield at the 2 against teams with poor coaches (like Melbourne) or teams who lack the defensive personnel to exploit such a lineup (Wollongong), but if you try it against Perth you will end up with egg on your face.
It also depends on player development: Blanchfield is still young, and Steindl -- while a few years older -- is still a couple of years away from his prime, so there's room for skill development yet. If I was Dennis I'd be assigning an assistant coach to just work with those guys all offseason on ballhandling.
In reality though... if they want to win (and assuming both guys don't make any strides in the ballhandling / decision-making departments) you will probably see Norton, Markovic and Djeric getting most of those minutes at the two spot, with Steindl and Blanchfield playing at the 3 and 4. From memory last year, Blanchfield was used very sparingly at the two spot, but he did at least see SOME time there.
Blanchfield doesn't really make mistakes though, because he is a very risk-averse, super-efficient player (sometimes to a fault), so I can't see why he couldn't play a few more spot minutes at the two. The other equalizer there is that Jacob Holmes can handle the ball, so if he is on the floor at the 4 spot you have more room for error with a guy at the two who isn't a ballhandler.
I think the best way to run this squad would be starting both PGs in the backcourt...you have an insane amount of lineup flexibility, and the only thing you are missing is a big, true shooting guard (a position that is becoming redundant in the modern game anyway because everyone can shoot it nowadays):
Markovic / Norton / Djeric
Norton / Markovic / Djeric / Blanchfield / Steindl
Blanchfield / Steindl / Henry
Conklin / Holmes / Steindl / Blanchfield / Henry
Gladness / Vanderjagt / Conklin
Might be the most versatile team the Crocs have ever put on the floor:
- Multiple guys who can play at least two, sometimes three different positions. -Solid defenders at every position who can guard multiple positions.
-Shooting at every position except the 5...like really good shooting. There are 5 guys on this team who shot 40% from deep last season. FIVE!!! That is ridiculous for an NBL team.
-Rebounding & size at every position.
-Athleticism and youth at every position.
If Dennis plays his cards right, there are myriad matchup nightmares that he can exploit...this team has a high ceiling...it just needs to find an identity and toughness early.
And forgetting all that, it's gonna be fun as hell to watch this team run and dunk over everyone, even if they don't end up winning as many games as they should.
