The Oakland Raiders may have overcome enormous and perpetual obstacles to earn Las Vegas Stadium Authority and NFL approval for their stadium build in Clark County. However, fans still don’t know an exact figure on how much the domed facility will cost according to Las Vegas Review-Journal’s Richard N. Velotta.

The original projected cost of $1.9 billion is nothing more than an educated estimate on what a practice facility and stadium will cost according to Velotta, who went on to reveal some other eyebrow-raising holes in the team and county’s agenda.

Bank of America never officially announced how much of the $650 million that Raiders owner Mark Davis needed they covered, nor the actual terms of any arrangement per Velotta.

Moreover, other questions remain unanswered such as the limited public information being released on the Clark County hotel tax that will fund $750 million of the stadium build, as well as several potential loopholes in the Raiders’ contract with Mortensen Construction that could impact taxpayers, per Velotta.

Pro Football Talk’s Mike Florio also reported Monday that the team could be facing litigation for their Las Vegas move, citing lawyer Jim Quinn who told SportsBusiness Journal’s Daniel Kaplan that “we will look at all legal options,” to keep professional football in town.

“There may be some legal claims that can be asserted,” Quinn elaborated per Florio.

The stadium is set to be located at the Northwest corner of Interstate 15 and Russell Road in Las Vegas and is currently scheduled to be completed in time for the 2020 season.
