Michels and Verba were Wolf picks. So was Aaron Taylor, who was a decent player and a R1 pick as a Guard (!)

Best DL drafted since Wolf was probably Kenny Clark. You could make an argument for KGB, but if we're talking about R1 it's KC. The Packers' track record of drafting DL early has actually been... not good. The DL draft classes have not been great lately, although Karl Brooks could be a steal.

You can find value at any position later in the draft, but you still need high end talent to handle another team's high end talent.
If your OT is a late round guy with limited athleticism, there's a good chance he's going to give up one or two sacks in a game vs. Bosa, and that could change a game (or put your QB in the hospital).
You absolutely need to minimize that risk if you have a chance to.

I love some of the WRs in this class, but I just don't see them taking one in R1. It'll more likely be a Yokozuma, so get your crazy hate mail ready for Gute if you don't like it.
