Yeah, I'm skeptical too but drafting 6th in a 10 team keeper league my thought is by the time I pick there isn't going to be much for 1st round caliber players available to select from so from a value perspective I think keeping Ekeler who will then be the #6 pick of the draft then targeting the best WR available with my 2nd round pick is my best path to getting the best players available with my early round picks. Tony Pollard and Garrett Wilson were 2 guys I was hoping to consider using my keeper pick on and I would have probably used it on Wilson had I had a top 3 pick in the draft with some options to nab one of the top players without having to use a 1st rounder on a keeper. At pick 6 in a keeper league I could be looking at a pool of guys that would be late 1st/early 2nd round guys so Ekeler to me is the safer keeper pick for where I am drafting.
I need to start researching who I want to target, I'd like to go Ekeler then WR WR then see what makes sense for best available WR/RB/TE positions in the 4th round. Last year I drafted my QB in round 7 which was Hurts and that panned out really well but I think he is off the board in the 5th or 6th round at worst this year given how the guys in my league like to target certain QBs. My sleeper target at RB this year kind of like Pollard was for me last year is Rachaad White. He should see a lot of volume and not much for depth behind him on the Bucs roster and he's going somewhere in the 60's overall in drafts.
I'd keep Pollard. I think he'll end up with roughly the same points as Ekelar and I'd rather have the sixth pick than the 19th pick.
