3rd String QB

I need a 3rd string qb to put in my OP spot.. Should i put up with Trent Edwards or Cassel?

Point breakdown:
Every 10 passing yards (PY10) 4 Each Pass Completed (PC) 2
Every 5 pass incompletions (IP5) -2 TD Pass (PTD) 15
Interceptions Thrown (INT) -15 2pt Passing Conversion (2PC) 5
300-399 yard passing game (P300) 10 400+ yard passing game (P400) 15
Sacked (SK) -5

Wide receivers can put up the same points as a QB if they have a decent game and the best ones avaiable are :
Ted Ginn Jr.
Amendola
Mike Thomas (Jac)

Whatcha think?
TIA any help is appreciated
