I've been reading this board for a while and I just joined so I could comment on this signing. Here is the write up I did for Realgm, I think it kind of sums it all up.
I'm really excited about this signing.
I think Miles might be able to take over some of what Posey gave us, a long athletic defender for three's and quick fours. People say Miles wasn't a good defensive player, but he always got some blocks, and always had the natural ability to play, I don't think it's out of the question to think that Thibs, KG, and our system can get the best out of him defensively.
Also, he has sounded very mature in interviews regarding his comeback. I don't think he is the same young kid who was a cancer, I would like to think (maybe hope) that he has grown up. He said all he wants is to come off the bench for a contender, and he certainly has that opportunity. He said he wants to sign, move to his new city and immediately start working out until training camp, and I'm looking forward to Globe and Herald articles in the near future that report something to that effect.
It was also reported that he and Pierce are good friends. Its also no secret that KG was his idol growing up. Even though he is already 26, I think KG will take him on as a personal project. If Miles can be a productive member of any locker room, let alone team, its this one. He also is going to have every opportunity to succeed on the court.
I think he has a good chance to become our primary back up SF. The only thing I don't like is that it takes min. away from JR, and potentially a spot away from Walker, although I think we should still sign him as insurance. But that is more just a binky thing, if he is productive I'll be happy.
If for nothing else this gives us some interesting lineup options if he is healthy, here are a few I'm looking forward to seeing now that Miles is part of the fold:
Rondo/Ray/Pierce/Miles/KG
Similar to how Posey came in first in most games to spell Perk
Rondo/TA/Giddens/Miles/KG
Potential to be an extremely athletic and great defensive team. Great video game lineup.
Ray/Pierce/Miles/KG/Perk
If we want to go big, Miles has shown that he can be a decent facilitator for his player type.
I echo what almost everyone else said, great low risk high reward signing. If this is a Dahntay Jones or Brandon Wallace type deal, I'm not sure how it can be seen as a negative thing.
