I have a hard time separating "players I love" from "players who can do no wrong." Additionally, I love all celtics, but I am more critical of others.
Disclaimer: I despise "intangibles." though I believe that intangibles exist, I firmly believe that 90% of the time, if someone says that a player has "intangibles" as a positive quality, what they really mean is that they inexplicably really like a player whose surprising unproductivity does not mesh with their mental image of a player's production, but because they want the player they like to be "good" player, they use "intangibles" as a positive attribute, because it is essentially a bullet-proof argument. (after all, if you don't see the inangibles, it's not the player's fault, it's YOUR fault for not being sophisticated enough to recognize intangibles.)
That said, I love tony allen, but he isn't a binkie. If he were traded in the right deal, i wouldn't lose too much sleep. I think that he tries extremely hard and works hard to get better. he lacks elite natural talent (i think he practices his ball handling, but some people, no matter how much they practice, have a ceiling) and he's battled injuries, but i think he brings more to the table than he takes away.
Powe is a binkie. I think this is because I was touting his virtues during his college season (after all, during those miserable seasons looking forward to the draft was half the fun of being a celtic fan). I firmly believed that he was a lottery talent who fell because he had injury issues. since he is basically injury free, i'd say he was a major steal, and i love watching him improve.
Now that he's won a title, Pierce is a binkie too. I want him to retire a celtic and play in one jersey for his pro career and enter springfield as a celtic only.
Noting my disclaimer above, players who are disproportionately valued due to intangibles i tend to be harsher on than average. i still like them, but for some reason i feel a need to bring their reps back to earth. for example, i think many people view Big Baby and Powe as equivalent players, with Davis's intangibles making up the enormous difference in talent and actual production. after watching tons of celtics games, i just do not buy this. powe is simply better, and i'm easily drawn into discussions about this.
I think posey was a very valuable player, but considering he was the 6th most important player on our roster, i think he became quite overvalued. still like him though, as i like all celtics.
