Ultimately, Posey is potentially worth the price of another title. This is the same argument that some of us were having about 10 months ago when some people were looking at guys like Patterson and Udoka as equivalents to Posey, and that's simply not the case. He does more than give great defense, he does more than hit big threes, he basically does every little thing it takes to win. Moreover, as Allen begins to age, Posey is the perfect guy to have around as he can play 25 mpg and not give us a huge drop-off.
Plus, you also have to ask yourself what else we need the MLE for? Who else could possibly give the C's the production of Posey? Sure, there are people who could score more, but that isn't what this team needs. On top of that, while there are other holes besides the 2/3 spot, we should be able to fill them much the same way we got House, Cassell, Pollard, and Brown this year.
