The Boston Celtics just splashed the cash on Marcus Smart. This came out to the tune of a $77 million, four-year extension, which by his own admission, has Smart himself jumping in joy.

Then again, there appears to be one lingering issue for Smart that money just can't solve. According to Celtics insider Tom Westerholm of, Smart is still feeling “a little stung” about the fact that he's always played the role of a second-string guard in Boston:

To be clear, Smart does not appear to be completely unhappy with his situation at the moment. After all, he did sign a massive extension with the Celtics. If he was truly displeased with his predicament then he should have decided not to put pen to paper on that deal. Then again, no other team in the league was likely going to pay him that amount of money, so in the end, it's a win-win situation for both Smart and the Celtics.

The good news for Smart is that Kemba Walker is now out of the picture. Walker is now with the New York Knicks, which should open up a starting spot for Smart. The only threat that stands in the way appears to be incoming sophomore Payton Pritchard. Then again, if the highly-promising 23-year-old is somehow able to pull ahead of Smart in the pecking order then this clearly won't sit well with the veteran. It should be an interesting year ahead for Boston.
