Ken, I think it is a good pick, but as you say, I think it is a gamble. He has excellent natural talent, but not quickness like Donald (perhaps no other NFL DL does). And, he was a bit of a late bloomer. RS freshman season (admittedly competing with a very talented DL). Decent but not dazzling contributions next year, and then as a starter just got better and better as a starter as the year went on until he was defensive MVP in the national championship game.
As an AL fan / resident (as well as a NEP fan), I am "all in" with the AL Mac Jones pick, great pick / gamble and certainly a perfect match for NEP.
IN contrast, for Barmore, I'm not really sure, I agree with you that my opinion of Barmore is: "we will see". If continues to develop with good hard coaching like he did in last year (and especially late in the year especially the playoffs) at AL, he could be amazing. But, he isn't really a classic BB type.
