The Cowboys have restructured the contracts of All-Pro left tackle Tyron Smith and All-Pro center Travis Frederick, freeing up roughly $17.3 million, moving them under a proposed salary-cap of $168 million for 2017, according to sources. The total cap will be finalized by March 9 when the league year begins. The Cowboys turned roughly $21 million of the $24 million due Smith and Frederick into signing bonus to create the room. Smith was set to make $10 million in 2017, while Frederick was set to make $14.221 million.
