Luka's leg, Rangers' arms and the hole in the Cowboys

SportsDay Insiders Kevin Sherrington, David Moore and Evan Grant discuss [2:40] the impact of Luka Doncic's calf strain on the Mavs' playoff hopes starting Saturday against Utah. Despite the uncertainty about Luka, Kevin says the best thing the Mavs have going for them is their finest defense in decades. David says the measuring stick for this season will be how the Mavs fare should they advance to face Phoenix, the best team in the league. [15:38]  Evan says it's too early to worry about the Rangers' bullpen, while Kevin says dithering without adding arms could burn up the hopes of players and fans alike. [31:18] And David talks about the unusual depth of this NFL draft and what it could mean for the Cowboys in rebuilding their offensive and defensive lines.   Learn more about your ad choices.
