SportsDay Insiders Kevin Sherrington, Evan Grant and David Moore discuss the end of the Mavs' season and its impact on Jalen Brunson's future as well as the start of something -- maybe -- with the .500 Rangers. [2:00] Kevin asks Evan if Corey Seager's 11 home runs -- including nine at Globe Life Field -- are a good sign considering he's under contract for 10 years. [13:30] In order to find a center who can rebound and provide a little interior defense, David predicts the Mavs will sign Brunson, give Tim Hardaway Jr. a little time to reassert himself then decide which of the guards to deal during the season. [28:00] And Kevin and David discuss DeMarcus Lawrence's new dreadless look and just how much better the Cowboys' defense can get in Dan Quinn's second season as defensive coordinator.
