SportsDay Insiders Kevin Sherrington, Evan Grant and David Moore [4:00] discuss whether Jalen Brunson stays with the Mavs, a team he likes and where he has a better chance of winning, or does he go to the Knicks to run the show and play for his father? Evan says a pro athlete's decision invariably comes down to money and a shot at winning, but David notes that family may change the dynamic. Jalen may also have a bone to pick with the Mavs. [17:30]  Evan points out that Corey Seager may not help himself by taking a private approach to his hitting slump. Metrics and scouting allow teams to make faster adjustments, Kevin says, and hitters need all the help they can get. [30:22] And the insiders discuss the impact of Arch Manning's commitment to Texas, a program historically low on QB talent.
