I actually think Washington could be a real contender depending on how Wall and Beal develop. They aren't ever going to be one of those consistent contenders like San Antonio, Miami and Boston, etc., but I could certainly see them in the Orlando (with Dwight) mold, which is a lot different than Atlanta has been.
I agree with Moranis.
I think if Beal and Wall become All Stars, particularly in the next 2 seasons, they'll be able to attract a major free agent to the city and even without that major FA, they'll be contenders in the East for the next 7-8 years.
Keep in mind that the Wizards long term goal is to sign Kevin Durant, because Durant is from Washington and he's said the only place he'd leave OKC for is Washington.
Pierce is only on a 2 year deal, he's tradeable next season as an expiring to someone like the Clippers, and Gortat is a solid rebounding big man who does an okay job of protecting the rim.
