They have usually been decent at drafting WRs in the mid rounds of the draft, but they need someone who can make immediate impact and that's tough. They may have to let one or two go on defence to allow cap space to go after a free agent receiver. Beckham is the obvious one to go for, but his injury is the big unknown. If he's going to miss half of next season, it might not make sense. I don't really know if there are good options available in the draft, but a catching tight end is pretty important too.
Special teams can't really be much worse, so the only way is up. I think they should definitely look for a return specialist late on tomorrow.
