When the game is on the line, who is the guy keying in on the opponentās best offensive threat? Here are the five best perimeter defenders in the NBA today.
Defense wins championships, even in a high-scoring game like basketball. Making it difficult for an opponent to put the ball through the hoop only aids in a teamās quest to win an NBA title. Though rim protection may be a more obvious sign of a good defense, there is a lot to be said about the lock-down defenders out on the perimeter.
The NBA has a dearth of elite wing defenders in the pace-and-space era. Itās insanely difficult to hold oneās own in on-ball defense without being allowed to hand check. Yet, these five defensive stars still seem to do just fine on that end of the floor.
Here are the five best perimeter defenders in the NBA entering the 2016-17 NBA season:

5. Tony Allen, Memphis Grizzlies SG
Memphis Grizzlies shooting guard Tony Allen will beĀ 35 years old this upcoming NBA season, but he is still one of the best lockdown perimeter defenders in the game. Allen has cultivated a fine NBA career for himself with defensive acumen and is a five-time selectionĀ of an NBA All-Defensive team during his time with Memphis.
Last year might have been a down year for Allen but this probably had to do with him missing 18 games for the 2015-16 Grizzlies and playing on a team with a ton of also-rans once a litany of injuries set in mid-season. He was still second All-Defensive last year.
Since arriving in Memphis in 2010, Allen has been the best perimeter defender over that lengthy stretch. His 1.7 steals per game, and 2.7 defensive Box Plus-Minus has made Allen a defensive dynamo for the Grit Nā Grind Grizzlies. Even though heās generally a minus on ofense, Allen is responsible for 16.5 Defensive Win Shares and a 10.0 VORP overĀ the last six NBA seasons.
Allen is by no means a Hall of Fame caliber player. However, his No. 9 Memphis jersey will one day hang in the FedEx Forum rafters when he calls it a career. Age is catching up to Allen, but heās this decadeās version of Bruce Bowen: the best defense-first perimeter player in basketball.
