Due to relocation from Chicago to western PA, last night was the first time I've seen the Celts in person in 18 years. Here are my thoughts based on what I saw:
1) POB is very athletic and more skilled than Perk. He's longer, quicker, has better hands, better touch and better timing. He needs more lots of work and experience. I doubt he ever reaches Perk's level for tenacity, desire or strength of character. Plus Perk is much more physical.
2) Miles is a great athlete. His shot is very rusty but he has great moves around the basket and passes well out of a double team.
3) Leon Powe is tremendous. He can contort his body and get a good shot off against almost anyone. He reminds me a lot of old number 31.
4) Gabe Pruitt struggles to run the point but is a player. He can shoot, run, jump and defend well enough to contribute.
5) Big Baby appears to be in better shape.
6) The team of House, Pruitt, BBD, Powe and Tony Allen dominated the Cavs scrubs down the stretch.
7) Ray Allen will be better this year. He looked like a young colt and even posted up once for a score.
8 ) PP and KG are still dynamite.
9) Most impressive was that the entire Celtics' bench (players) was on their feet for most of the 4th quarter, cheering on their teammates. To have 3 superstars that care that much is rare leadership in today's sports world.
The 2nd unit (any combo of POB, Powe, BBD, Miles, TA, House, Pruitt) can be one of the best in the NBA if they jell. Doc has a lot of options with these 7 and Sam to mix and match. They have the skills and athleticism to match up with any team and give the team a lot of quality minutes. I think they will be better even with Posey gone. If they are affected by the loss of Posey it will surface more in the playoffs than in the regular season.
All of this opinion is based on watching 1 preseason game, so take it for what it's worth.
