They tries to get Mahomes.
The draft is a crapshoot. Look at how many quarterbacks or players at any position wash out without being successful.
I wouldn't have drafted a quarterback while trying to win with Drew unless I felt there was a cant miss prospect. Like Payton must have felt about Mahommes. Not while those picks had a chance to be used at other positions to help us win then. You just never know and hindsight is 20/20.
If you are going to be critical then you should at least try and be fair and reasonable while doing so. You'll look reasonably intelligent for it.
