Did the Dallas Cowboys overpay for Dak Prescott???
Perhaps ... but that's OK, according to Drew Pearson -- who tells TMZ Sports his former team should be happy with re-signing their star quarterback regardless!!
"Maybe he's not worth maybe 40 million dollars a season," the Dallas Cowboys legend said. "But, that's the market. That's the value."
Pearson added, "It's good for everybody."
27-year-old Dak ended a 2-year-long dispute with the Cowboys earlier this week by signing a 4-year contract worth up to $164 MILLION.
