I guess my point is, look at the teams that are actually "contenders". They all have guys they can stick at the 5 who are capable of switching on to smaller players and not be a total liability. Teams like Toronto, Boston, Golden Sate, Milwaukee they all have more traditional bigs in case of match ups but generally where they do the most damage is with their switchable line-ups. It's why I had a guy like Jaren so high on the board last year and why I still think he's the best big man prospect in the class. Of course, there are more defensively challenged bigs who are so good offensively that it alleviates some of their defensive deficiencies but how many of those guys even exist? 1? 2, maybe? Outside of floorspacing, defensive versatility is the most important thing I look for in players, especially bigs.
