Vesely is a better player than he's shown for much of this season, but early failure has robbed him of much-needed confidence. That has morphed him into a player who sometimes forgets that energy alone is a valuable talent.
No player has more of that talent than Wallace, who knows that playing as hard as possible without a great skill set gives his team a better chance to win. Wallace knows who he is and brings that player to the game every night. Vesely has the length and agility to make a lot of hustle plays, and if he focused on that every night, he would be on the right track toward becoming the player the Wizards expected when they drafted him.
