I don't have much hope that they will accumulate picks at least not unless they trade Lattimore, but those picks would likely be for next year given they can't really trade him until June 2. I have some hope that they will stay where they are, but I wouldn't hold my breath for a trade back.
As far as Haener, I'm all for giving him a shot to develop, but I also think they need to take a QB in the draft every year until they hit on a guy either in the early rounds or in the mid to late rounds like Purdy, Russel Wilson, Dak, etc. Even our greatest player of all time was a QB picked in the 2nd round. So, keep taking swings at one every year until you find one. Haener can compete with the draft picks and let the winner start.
