NEW YORK >> When D'Angelo Russell went down with a pair of leg injuries late in January, it was tough to know exactly where he stood. A strong month had given way to struggles, and he didn't play in the fourth quarter of consecutive losses.In his three games back on the court, however, Russell has recaptured what made him so successful earlier in January, prompting Lakers coach Luke Walton to leave his 20-year-old point guard on the court for at least 31 minutes in each game.
