Horford will NOT be playing the 4. I've seen it advocated far too many times.
I know a lot of people like to take a roster and parce out players with potential for an increased role (Horford) and throw them into a lineup w/o considering the coach, the system and the role.
Barring a major change in philosophy (not impossible) from Coach Beilein, we will stick with our "5-out" / "1-post" offense. While being relatively adaptive, Beilein knows what is takes to make his offense work, structures his lineups in a manner conducive to scoring and is very creative with defensive tactics (1-3-1 /2-3 zone, smart double-recover schemes) to hide the deficiencies that playing unorthodox creates.
All it takes is one look at what Novak and Smotrycz do at the four spot in this offense to realize that Jon Horford will not be able to do these things.
Horford is strictly a 5 as are Morgan and McLimans. Playing for other coaches, things might be different. It is good to have depth at center and it presents a bit of a roster inefficiency where-in 40 minutes seem too few for Jon and Jordan, given their potential. That's where we see uninformed posters try to cram Horford into a role on this team for which he is unsuited.
Do any of you see Horford running off of screens? Driving after a shot fake? Cutting back door? If you do, you need to get better at watching basketball. If you don't and you still think Coach will stick him in at the 4 to 'get our size on the court' and 'let Novak play wing', you need a reality check.
Smotrycz will get most of the PF minutes next year and Novak will likely get most of the backup minutes there while starting on the wing. Horford may tantalize with ability at times, but he and Jordan will get no more than 40 mins together. Just how good Horford becomes will determine the rationing of minutes at the 5 and not how many minutes they should play together. Beilein's offense works because of spacing and playing one big creates that. He has a track record at Michigan of playing only one big and while that could change in the future, I will believe it when I see it
