Celtics Pride is rare indeed these days. I think Marcus Smart on the present team shows the most Celtic Pride. Sullinger to me is the opposite, his loyalty is too himself and he likes to cast blame about and does not try on D. To me, he has the wrong kind of pride, Hubris, and he comes into camp out of shape and speaks like he is all world.
Guys like Green and Bradley, I almost have to question if they have any pride because their effort level is uneven every night. KO and Zeller are wimps and lack confidence the moment they miss a shot and are very slump prone.
Pride is about being proud who you are in sports and not letting the other team embarass you or your team. It is about representing, for your team mates and your city in a positve manner and with great effort. In war, you fight for the guys besides you and so you can go home to your loved ones. It used to be like that on a team, your played with your team mates but free agency has changed it so your playing more for money.
As for the loyalty, I think the whole " this is a business" culture in free agency has really put in a dent in the whole loyalty thing. A GM has different loyalty nowadays than the team. His job is to make the team better and sometimes that entails making it worse for the lotto or letting a valued team mate walk when they are wanting paid beyond their production.
