Morgan and Speilman had big numbers last season because of the Riley offense and the fact they were always coming from way behind slinging the ball around.
Morgan and Speilman are good WRs, but they are not the best in the conference. Speilman and Tyjon have real potential. Morgan has great hands as a possession receiver, but not elite speed or moves. A good stiff arm is his best weapon.
The offensive players Frost brought in the overhaul the roster and provide the speed and big play ability haven't shown they are really elite. Martinez has had some big plays, but the RBs get caught from behind and the WRs haven't been able to break big gainers for TDs.
The offense is dink & dunk and moves the ball, but doesn't get into the endzone enough.
