Terrific signing. Terry is an excellent player who knows how to win. He is clutch. He has the swagger of a champion.
Now they need to sign Ray, too. Not only would that give them a great 4 guard rotation but they can play small ball with a lineup that will drive other coached batty:
KG
Pierce
Allen
Terry
Rondo
Late in the game, when you go offense/defense, you can sub in a big and Bradley for Allen and Terry.
Also, a great 5 to close a game when the other team has to foul. The last 5 years, in those situations, Rondo would throw it in and look for Ray first, Paul 2nd. Now Rondo will still be the trigger man but can look for either Ray or Terry, Paul third, KG 4th. All are good FT shooters.
