Dan and Andy deliver Part 2 of their top-25 lineup series with Nos. 10 through 1. Did your favorite team's favorite lineup make the cut?  But first: The Sixers announced Joel Embiid will be out indefinitely after entering the NBA's concussion protocol and also suffering an oribital fracture that will require surgery. Sources told ESPN.com's Zach Lowe that The Process could feasibly be at risk of missing the first round of the playoffs.  Can the Sixers survive without him, not just for the rest of their regular-season schedule, but when the stakes soar in the postseason? Might they still be able to steal the Eastern Conference's No. 3 seed from the Cavaliers? Finally, if you were looking for some John Wall trade ideas, you've come to the right place. Dan and Andy have one of those, too. As always, be sure to subscribe to and rate Hardwood Knocks on iTunes. You can also find us on Stitcher and BlogTalkRadio.
