Where can I find stats for steals and offensive fouls against by team? I gotta imagine we're Top 3 in both.

82 games is a good site for things like this. Here is offense fouls against

82 Games is most frequented for more than the basics.

The other one I find useful is basketball reference.

I don't know if this is what you were after, but if you go here, scroll down to the "Misc Statistics" section, under "Defensive Four Factors" click on "TOV%" and you'll see Miami opponents turn the ball over more often (% of possessions that end in turnovers) than any other team in the league.

Similar to Mopper's link (same site) but I like to use the team stat page instead because it has the team stats right above the opponent stats with the ranks for both under the "Team and Opponents Statistics"
