Evans practiced all week, albeit on a limited basis. He first suffered the hamstring injury during week two of the preseason and hasn't played since, in part because Lovie Smith is very cautious with hamstring injuries. Evans' absence probably hurt the offense in week one, but it was hard to tell given the general lack of competence displayed in that game.
That said, Evans' addition should help Jameis Winston complete some passes to a receiver not named Vincent Jackson. If the Bucs can keep Winston protected, Evans could have a pretty big game against a fairly weak New Orleans secondary.
