My assumption is that Groot and Boogie now are through the "rookie wall", see how long the season really is, will work on getting better and bigger for next season in an real NFL off-season conditioning program and make a bigger impact come July, August and beyond. Horrible Harry , same thing, instead of re habbing a major knee injury in the offseason and then playing all season with another injury, he can recover (unless he needs another surgery . ). and have a real off season of conditioning and come back fully healthy and stacked. Plus Hughes/Addison could not play full time anyway.
Thank goodness McD had a rotational scheme to get over all these individual players issues.. If AJE, Groot, Boogs, and Harry step it up a level this year, we may see them taking more snaps than they did in the past. McD is learning I believe
