Heineke had a 12/6 TD/Int stat in 9 games compared to Wentz's 11/9 TD/Int stat line in 8 games....Heineke also took 19 sacks to Wentz's 26....and while their Comp %'s were similar Heineke had a 7.2 ypa average compared to Wentz's 6.4....lastly Heineke as a starter this season was 5-3-1 compared to Wentz's 2-6 record.
So while Heineke is not a Top 10 QB, he was the clear QB that should have started and the only reason Rivera might have started Wentz is because he is simply clueless and should be fired immediately.
As for tanking for Bryce or Stroud, Washington currently stands at #14 in the NFL draft and have absolutely ZERO chance of getting anywhere near a Top 5 pick so unless they trade the farm to move up do not expect Washington to get either of those players. The best Washington can possibly do is move up slightly to grab Florida QB Anthony Richardson who at 6' 4" 232 pounds and running possibly a 4.5 40 yard dash could be the boom or bust pick Washington needs.
