Thanks to Mook for the talking point.
Recent NBA Champions:
2008: Celtics, featured not one, but two fine wing defenders to stop Kobe Bryant - Paul Pierce and James Posey. The Lakers best wing defender is also the number one option, thus they didn't have the ability to shut down Pierce.
The Celtics with their two solid wing defenders got past LeBron James in the semis.
2007: Spurs, with Bruce Bowen (and Ginobili, who is actually an ok defender), were able to keep LeBron from single handedly winning in the Finals.
2006: Miami Heat, with James Posey, beat the Dallas Mavs, a better team.
2005: Spurs (Bowen) over the Detroit Pistons.
2004: Detroit (Prince, but with lots of team defense help from Ben Wallace, Rasheed Wallace, etc.) over the Lakers.
2003: Spurs (Bowen) over New Jersey.
2002; 2001; 2000: Lakers (Rick Fox) over New Jersey. Actually, here is our first example. Fox wasn't all that as a defender. Decent, but not in the class of the above guys. This Lakers team wasn't about lockdown defense like the Spurs. They played above average defense and outstanding offense. Fact is, they had Shaq and Kobe. Just try to stop them from getting a bucket. You couldn't. Thus, defense was important to the Lakers but not essential.
1999: Spurs. Another example. No Bruce Bowen yet. Had the Twin Towers defense with Duncan and Robinson. All wings had to do was funnel guys into the teeth of the defense.
1998 and for many years prior. Bulls, Bulls, Bulls. Scottie as the defensive cake, Jordan as the icing. If they didn't want you to score a bucket, you probably didn't, as a parade of Hall of Fame offensive players found out.
Do we absolutely have to have a lockdown wing defender?
No.
Are we giving ourselves the best shot at making regular shots at the title without a lockdown wing defender?
I don't think so.
