WR is the only area where we may have made a slight upgrade, but I personally don't see it.
How on earth can you "not see it"? Let's take a look at the roster:
Lost
Dorian Graham - Extremely replaceable. Good kickoff return guy, but couldn't beat press coverage and struggled getting in and out of his routes.
Van Chew - When healthy, was a pretty good WR. But he was very rarely healthy.
Kyle Foster - Injured. Coaching staff was high on him, disappointed he will miss a golden opportunity this season.
Michael Acchione - Walk-on who saw playing time. That should tell you how poor our WR corps was last year.
Added
Marcus Sales - 4-star recruit - Always has had talent. Breakout game in Pinstripe Bowl, have to think he will give everything he has with his second chance...
Christopher Clark - Not sure what we will get from him. Has a lot of speed, and from his film it looks like he has more natural receiving ability than Graham did. How quickly he adjusts both from CC and from injury will be interesting to see.
Alvin Cornelius - Big, strong receiver that will most likely redshirt. Hopefully. If he's in the mix for playing time then I will be disappointed.
Ben Lewis - More of a possession type of receiver. Again, like Cornelius I like his future but I think he needs to redshirt as well. If he plays, we have some injuries and
Returning
Alec Lemon - He is healthy this season, and primed for a great year IMO. With Sales returning, the two of them can help each other create mismatches for defensive backfields. He is a very good football player, and I don't think people give him enough credit.
Jarrod West - Coming off injury last season was very inconsistent. Should be fully healthy now, and with a full year in the system and spring ball, I expect that he will become a viable option in the rotation.
Jeremiah Kobena - Was also nicked up last year. From reports, he's running extremely well. Hope he can remain healthy this year, he has legit top-flight speed and if he can get into open space he can become one of the "playmakers" that so many are longing for.
Adrian Flemming - Third year in the program after having his redshirt season (mistakenly, IMO) burnt for a game or two. Big kid, can potentially be a red-zone option similar to what the staff had hoped Foster would become last/this year.
Keenan Hale - Haven't had a chance to see him play yet, but similar frame as Flemming
- big kid, can really jump (HS champion in high jump in GA)... Don't expect him to have much impact but you never know.
So in conclusion, I would have to think this year's version of Alec Lemon will be better than last year's version if he remains healthy.
Moving down the list, last year's #2 - for argument's sake, we'll say Van Chew, is replaced by Marcus Sales. I don't think there's any doubt that Sales is better than Chew. And potentially by a long shot.
#3 - Dorian Graham vs. Jeremiah Kobena. Remains to be seen how Kobena can catch the ball, but as a football player I like his shiftiness and ability to make a play more than Graham's. Give Graham the edge with experience. Both have had their issues catching the ball. Both are/were good KO return guys. We'll give slight edge to Graham.
Obviously not having Foster this year is disappointing, but he wasn't a factor for the team last year either. That's a wash.
Then you add Clark, who has speed, and then the rest of the guys are a year older and presumably more adjusted to D1 football. And hopefully in better shape and bigger. The two freshmen are a bonus.
I'm not sure how anyone could "not see" how this year's WR corps is improved from last season.
