Heard he failed his urine test...seems he emptied his bladder in the parking lot, so there was nothing to put in the cup...
These signings (Johnson, Spaeth,etc.) are nothing to get excited or frustrated about. They are just cheap "fillers" for camp & preseason. They will be drafting a TE. If Johnson or Spaeth can't work their way up teh depth chart they will be cut with minimal-no dead money. Same happens with draft choices.
Plan may be Spaeth, Paulson, & Rookie. Miller starts on PUP...Give him time to heal.
