Using the data from basketball-reference.com, Avery Bradley shot 38.5% on jumpers in 2011-2012 (regular season), with 40.0% on twos 16 feet or more and 40.7% on threes. In 2012-2013, he shot 36.6% on jumpers, with 44.5% on those long twos and 31.7% on threes. Reportedly, his upper-body strength was diminished last season due to recovering from shoulder injuries, so that may have affected his three-point shooting.
For comparison, other Celtics last season on those long twos:
Rondo 50.8%
Terry 49.2%
Garnett 46.3%
Lee 46.1%
Bass 45.2 %
Green 38.5%
Pierce 38.2%
Some other notable shooting guards:

Can Avery Bradley maintain his improved shooting on perimeter twos while regaining some of his prowess from downtown? Will he regress on twos while getting back some of this three-point shooting? How good of a player will he be if he can play a full season shooting 45% on long twos and 38% on threes, with All-Defensive caliber play?
