You’re a long way from the season. There are still free agents out there. Players who will be cut. Players who can be traded for.
My point that you stubbornly refuse to comprehend is that often there are better options out there than wasting picks on WR question marks, in large part because for the general WR market it is better to judge players after they’ve actually played in the league.
Again, look to Belichick and all his Superbowl wins. Last year was the exception for them in picking a WR at all or up high. This year, back to no WR signings (though a number of undrafted signings right after the draft).
Any free agent worth a crap is gone within the first week of free agency. Guys cut weren’t good enough for their team. You’re talking about picking through garbage when they had opportunities to not.
What you miss is that draftees are cheap. Are they a crap shoot, sure, but they’re cheap. Way cheaper than free agents. Belichick builds the team through free agency AND the draft. They’ve drafted plenty of WRs. The draft is useful, if you’ve got the eye. And don’t obsess on stupid crap like wonderlics.
