I love Ben Lewis and Alvin Cornelius. Kobena had a great off-season, as did Flemming. Losing Foster and Hale hurts, but isn't the end of the day. Funderburke will be fine. Not a clue on Winfield, Estime or Cooper (ineligible anyways), but I'm sure one will be utilized simply because they were handpicked by the offensive staff and McDonald (my guess is Estime as a Tavon Austin-type lined up at the 3 slot). Chris Clark is intriguing and had a few nice catches last year, but I'd much rather see Flemming in there.
The biggest priority IMO is the WR's blocking ability (obviously we need guys to make some catches, but I'm really not worried as much as others about that). This will be a run-heavy team and we need guys that can stone the corners.
My guess for top 4 receivers at the end of the season:
West
Kobena
Funderburke
Cornelius/Lewis/Flemming
