The 2011 NFL collective bargaining agreement introduced significant changes to rookie compensation, including a rookie wage scale. We test if the new rules changed how sunk costs affect utilization for drafted rookies. Our regression discontinuity results show a robust sunk-cost fallacy that is similar in magnitude to the one documented under the previous agreement. Second-round selections play significantly less than their first-round counterparts, as measured by percentage of games started, total snaps played, and percentage of snaps played. However, the effect is not evident beyond the rookie season. Additional results show coaching success and coaching changes are important factors.

2011年NFL集体谈判协议对新秀薪酬进行了重大修改，包括新秀工资等级。我们测试新规则是否改变了沉没成本如何影响新秀草稿的利用率。我们的回归不连续性结果显示，沉没成本下降的谬误在数量上与先前协议中记录的相似。按照开始游戏的百分比，总的快照数和所占快照的百分数来衡量，第二轮选择的玩法明显少于第一轮。但是，在新秀赛季之后，这种影响并不明显。其他结果表明，教练的成功和教练的变化是重要的因素。
