I've been thinking about this topic for some time and feel the necessity to open this up for discussion. Today's NBA has EVOLVED dramatically from just a short decade ago. Today's NBA is downright dominated by ultra-quick point guards that can get to the rim at will. Think about it. Tony Parker, Chris Paul, Derrick Rose, DJ Augustin, Raymond Felton, Russell Westbrook, Brandon Jennings, Jonny Flynn, Rajon Rondo, Devin Harris, Aaron Brooks, Louis Williams, Mo Williams, Ty Lawson, TJ Ford, Mike Conley, Jameer Nelson, Gilbert Arenas are all PG's having a varying amount of success in the league today. I attribute this DIRECTLY to the no-hand check rule. PG play has burst onto the scene as one, if not the #1, attack from offense.
I then turned around and thought about how to defend against this HUGE in flux of quick PG play. And then I realized something. TYREKE EVANS. Geoff Petrie is AHEAD of the curve here folks. Taking a look at NBA PG's that can keep these guys in FRONT of them is minimal. Perimeter defense is at a premium. I see Chauncey Billups, Rajon Rondo and Russell Westbrook as the PG's today that are renowned lock-down defenders. The rest of these guys, don't offer much. If we're to be a good defensive team, it begins at the PG position. What better way to do this, than to stick a guy with a near 7 foot wing span that can potentially keep up with these guys. Even if he gets burnt occassional his heigth + wingspan often times can help him recover and still make a play on the ball.
This same holds true on the wing positions. Getting 'lockdown' defense from the perimeter is becoming more and more of a premium. If you look in the scoring standings it's DOMINATED by wing players and Point Guards. Adding Tyreke Evans to the fold is a way to help combat the lack of perimeter defense in the league to help benefit our team.
