I still think that is in the realm where you take your highest rated player regardless of position. Rookie drafts are all about getting starters for many years. Positions don't really matter much to me because if you take a lesser guy because the position is better but he doesn't pan out because he is a lesser guy does that really help you? Even if you get stacked at one position because your guys hit then you have flexibility because you have guys that are worth starting. I don't really factor in positions for rookie drafts.
I know I'm more of a lurker here, but just wanted to comment that I ended up taking the comment to heart about using the rookie draft to get as many long term starters as possible, and made a fairly significant change to the way I approached my rookie draft this year. Long post detailing picks/thought process influenced by taking some time to take this into consideration.
I've been in my IDP dynasty league for about 12 years and I still feel like a rookie when it comes to the IDP side of the ball, but while in year's past I would focus my attention on drafting offensive players and filling in the defense with FA pickups and late round draftees (and it has worked out okay for me), I fully intended to go heavy on WR in this year's draft (I had 4 picks in the top 24 (9, 12, 19 and 24), but after reading this and some discussion with another person I trust, I decided to buck my usual trend.
I traded the #9 pick for a 2021 1st and moving up from 24 to 17 (Reagor was on the board and is who I would have taken had I not traded)
At 12, I ended up taking Simmons (Queen went at 11). It was a luxury pick for me as I am very strong at LB already, but it gives me the flexibility to trade a guy like Lavonte David whom I have already received a few inquiries about. Took him over the 3rd tier of WR (Mims, Pittman, Higgins, etc.) and RBs (Dillon, Gibson, Vauhan, Moss) - we start 1 RB, 3 WR (2 flexes as well), and 3 LB, so while I could use WR depth, I figured Simmons really had the most likelihood of making an impact long term.
At 17, Higgins and Aiyuk were on the board as well as all of the previously mentioned RBs. As I have Guice, I ended up taking Gibson as insurance/handcuff plus boom/bust payoff. I'll taxi squad him.
At 19, I had intended to go WR to add depth, but this is where reflecting on this thought process came into play. Chase Young was still on the board. We are not the most DL friendly system (we start 2 DL, 3 LB, 2 DB and one DL/DB flex) but top DLs will outscore the lower end starters by about 3 PPG and are consistent. If Young performs close to projections, I can slide him into my lineup and no longer worry about fielding the hot hand of the week - basically one less spot that I need to churn, and as we use FAAB and count dead years against our contract cap, there are other benefits.
In years past, I probably would have passed on Simmons since I was already okay at LB and gone for one of the WRs and there is no way I would have considered Young there, I would have taken another dart throw on a WR or RB with a low probability of hitting. I can do that at pick 36 with just slightly lower odds of hitting. Hopefully the shift in mindset works.
All that to say thank you for the info - guess you can teach an old dog new tricks. The picks may not look as sexy as loading up on hyped up WRs, but I think it should have a more positive impact on my starting lineup which is the priority as I am in win now mode with this team.
