Portland's defense is a huge question mark. Sam Forencich Getty

The Portland Trail Blazers have a bunch of questions entering the 2015-16 season. Arguably the biggest one is do they have enough talent to stop opponents on a nightly basis?

The Columbian tries to answer that, along with four other questions, right here:

Portland has athletes, but they have little experience meshing with one another, and, pertaining to NBA defense, even more important than physical ability are intelligence and chemistry. Can the Trail Blazers communicate well enough -- and know where to be -- to stop the league's most complex attacks?

It's something we'll all find the answer to in no time.
