I think Jackson has a great chance to make the team. He's big enough and fast enough and was very productive at Syracuse.
Obviously, Woods, Kupp, Jefferson, Reynolds make the squad. Webster needs to be a specials teams demon, and if he call do it all on special teams, he makes the team. I love Winston as an UDFA. He's so polished that he won't be denied. Jackson might be the seventh WR if they carry seven, which they usually don't and might with a 55-man roster. People will see rookie UDFA and think he'll go to the practice squad year one, but if you remember during the draft how scouts were enamored with the deep WR class, then you might say some of the UDFAs have draftable grades and might hold the same weight as a draft pick.
