Pick & Roll: Roll Man (pick and rolls, pick and pops and the screener slipping the pick)


The Raptors had the 4th lowest total and frequency for offensive roll man with 475 and 5.5% respectively. But as a team they had the second highest PPP and first EFG% in the league.
It becomes more clear when you look at offensive ball handlers, where the guards like to get theirs, even if it isn't as good efficiency wise: http://stats.nba.com/playtype/#!/ball-handler/?OD=offensive&dir=1&PT=player
Pick & Roll: Ball Handler

Why in the world are they not hitting the roller/pop more? Is there an easy explanation?
The scary part is, Amir took 167 possessions all by himself. That accounts for a pretty significant 35% of these plays. The only saving grace is there really isn't a poor roller on the team.
JJ, in particular, is a rolling juggernaut where he was basically unstoppable (although at a measly 23 attempts).
So what's going to happen now? Do the Raptors shoot for an all time low of connecting with the pop/roller?
