Here's how I feel about the starting lineup -- when they're moving the ball and running plays, they look good to me. The skillsets mesh well, the size at each position looks OK, and they seem like a solid lineup.
But the problem is, they don't have enough offensive skill across the lineup to make it work. We need that lineup, basically, only a couple increments better offensively.
Example:
Smart --> George Hill
Bradley --> Bradley Beal
Crowder --> Demarre Carroll
Lee --> Derrick Favors
Zeller --> R. Lopez
See, if that was the starting lineup, we'd be great. But alas. Not so.
