Yeah, at the very least we need two viable options at backup. The Rams proved this last year. Jaime Martin was supposed to be the GUY be hind Warner, but when he didn't work out they turned to Bulger with good results.
But both Martin and especially Bulger were big question marks beforee they came in to start. Viable backups can come from unexpected places--ie Bulger and maybe McCown or Parsons.
I'm fine with going into the season with those two.
