Yeah, this is definitely where we disagree. Outside of Allen, none of those players are what I would call "good," especially for giving up the farm to move into the top 5.
Trubisky - Bad. Got run out of town and didn't even get his 5th year option picked up.
Goff - Mediocre at best. Was so "not the answer" in LA that they gave up two more first round picks to find his replacement, and that's after already giving up two firsts, two 2nds, and two thirds for Goff. Honestly the best on this list, but zero championships and playing for another team after five seasons isn't what you want for that investment.
Wentz - Bad. He had one great year but never even won a playoff game. The team around him was so good that Nick Foles won a Super Bowl with them. Didn't even get a second contract.
RG3 - Bad. One good year and then a complete washout.
Sanchez - Bad. The team won despite him. Somehow probably the second best on this list by the account of doing enough to win some playoff games and getting an extension.
Vick - Bad. Tantalizing to watch, but couldn't remain healthy, couldn't lead the team to the playoffs more than twice, and then got himself kicked out of the league for a bit.
Sorry, if you're trading into the top-5, it better be for a player that takes you to the playoffs and wins multiple times at the very least, and lasts for a second contract, if not makes you surefire contenders for the Super Bowl.
Also, not to overly nitpick, but the only QBs on your list here that qualify for jumping from inside the top 10 to the top 5 are Darnold, Trubisky, Wentz, RG3, and Vick. That makes the list even more painful to look at.
