When the time comes for Cowboys quarterback Dak Prescott to retire, he should consider professional poker as a new career. (We hear Las Vegas is welcoming.) The man obviously knows when to hold 'em and knows when to fold 'em. Negotiations over a contract extension between the team and Prescott dragged on throughout the offseason, with talks stalling partly over whether Prescott would take the team's five-year offer or hold out for the four-year deal he wanted. As a July 15 contract deadline neared, Prescott held pat, causing the team to place an exclusive franchise tag on its star and pay him $31.4 million for the current season. Contract talks have been pushed on down the road. Meanwhile, top quarterbacks are signing ever larger deals and an expanded salary cap in the future means Prescott could be in line for a bigger payoff, assuming he plays up to snuff this season. Some sports columnists say the team erred by not reaching a long-term deal for a player it obviously didn't want to lose, essentially wasting the franchise tag money. We should know better whether they're right sometime about the end of December.
