I think your article is on the money LC. Like you, I'd like to try and get Broekhoff into the team for that extra shooting, but also for his extra length and rebounding. I think he is fighting it out with Martin, Simmons and perhaps Bairstow or Jawai for the final spot. I think who makes it comes down to who performs in training camp and how Lemanis wants to play.
It looks to me like we are going to play small and press wherever possible (see Ingles comments, China series and Lemanis' Breakers teams) so I think that makes Motum extremely important and if he performs in training camp I could actually see him starting/ playing big minutes.
If that happens, then you have to question whether we need all of Andersen, Baynes, Jawai and Bairstow, who are all a little slow and best suited to play centre IMO. I think Baynes and Andersen are locks, but depending on how Jawai and Bairstow perform, you could possibly leave one of them out to create a spot for Broekhoff, whilst still having room for Simmons and Martin.
So, in that scenario, you could go with a lineup of:
Baynes Andersen Jawai or Bairstow
Delly Exum Martin
The risk there IMO is Motum's inexperience at international level. Lemanis would have to be very sure that Motum was ready to play a pivotal role. If he isn't then you are quickly putting a lot of pressure on Simmons, which he probably isn't ready for.
However, there are a few advantages with this lineup:
1) You are developing a style of play for the Boomers that will suit its personnel more and more as players like Simmons, Exum and Maker come to the fore in future years.
2) It allows you to keep Martin, a player whose skill-set and experience would be very valuable to this team if we are going to press a lot.
3) It allows you to keep Simmons on the team and gaining experience for a role that I think he is predestined to excel at in a couple of years.
4) It allows you to get Broekhoff into the team for his shooting, rebouding and extra length to disrupt passing lanes.
So while I'm not saying this is the team Lemanis will go with, I think it has some interesting possibilities to take advantage of the strengths of our personnel, both for this tournament and for the future.
