I liked the footage I did see of him. He looks to have good athleticism, strength and good aggression.
If, within in two years time, he could be a good back up for Rondo and also play some spot off guard when the match ups permit it, I would be very, very happy with that outcome.
Outside of Ainge wanting all his contracts to expire in two years for obvious reasons, I'm wondering how much his faith that Bradley could be a long term back up for Rondo and a spot back up at off, went into his decision to sign Nate for only two years? In two years time, if this kid is any good, he will be ready to roll...
