Weird signing tbh. I kind of wanted him on the Lakers because he can score, but he's not really a PG and I think that's what the Lakers need off the bench to give Nash a rest.
Rondo and Terry are obviously better than Barbosa, but so are Bradley and Lee IMO. That's why I don't understand this signing.
And yeah, these dudes are undersized but it won't matter. Boston is the second best team in the East and their biggest threat is obviously Miami. Wade is only 6' 4". Bradley can D him up even though he's smaller so that's not a problem. Terry being undersized wasn't a problem in 2011 Finals. Lee is 6' 5" and a solid defender. And like Stonezz said, I can't think of anything good for Barbosa lol.
Anyways, I don't think Boston can beat Miami so it doesn't really matter anyway.
