Welcome to the league, rooks!
The Seattle Seahawks' defensive back core held its annual rookie dinner Monday night ... and a pair of first-year NFLers were hung with a $17,500 check!!!
The booze-and-steak-filled night all went down at Daniel's Broiler in Bellevue, Wash. ... and according to some of the vets, it was the most expensive rookie dinner in a while.
The receipt is absolutely nuts ... the guys bought a TON of expensive food and alcohol, piling up $11,000 worth of Louis XIII alone.
There was also Wagyu steaks, lobsters, calamari and all the fixin's .
