In considering what type of defensive lineman the Packers need to bring in, I've been leaning more and more towards an upfield penetrating 3T.
While the Niners are certainly not a zone-only team, the Packers struggled to stop zone rushing attacks in 2019 in part because they don't have an upfield player along their defensive line.
The quickest way to run zone runs, especially wide zone, is by getting into the backfield and forcing the runner to redirect early.
So while it may seem counter-intuitive, I think the best way to bolster the run defense up front is not with a block eater, but with a player who wins early in the down-- basically with someone who actually is what they hoped Adams might be.
Javon Hargrave would be the cream of this particular crop this offseason, and more expensive than what Green Bay can afford (maybe 12-15M/season?).
Gerald McCoy is an interesting option who could be cheaper at 32. He played on a one year, 8M contract last year. Maybe something a little less would get it done this year?
Maliek Collins is another guy who might fit the mold. ******* his price tag is difficult. Maybe 5-7M? But he's young enough that if a team thinks he's still ascending, it could be much higher.
