Is Marcus Smart the sole reason for the Celtics current struggles? On this edition of the Causeway Street Podcast we debate if Smart's return is the answer to the Celtics need, plus why hasn't Brad Stevens been blamed more for the lack of effort on both ends of the floor? We also discuss Jayson Tatum's rookie slump and what to expect after All-Star break. Tune in and follow us on Twitter: @CausewayStreet, @Joe_Sway, @SeanDutra, @Joel_CSP
