I see these as internet know-it-alls that only know one part of the problem without the ability and knowledge to grasp the entire situation.
First and most important, what's the point of a Tennehill or other veteran QB. If we lose Jordan Love to injury, I would bet that 999 times out of 1,000 we will not win the Super Bowl with a backup no matter whom it may be. So in that scenario, why would we push to flame out on the playoff bubble versus just having a bad year and getting a better draft pick?
Second - does anybody really think it's a good idea to tie up $10-$15M of salary cap for a backup that will not win us a Super Bowl? I'd rather save that money for an in-season acquisition, or to sign one of our elite players.
Third - Bahktiari??? Seriously???? Fool me once, shame on me. Fool me twice.... We all love Bahktiari but he's got a bad knee and hasn't recovered. He can't get any other desperate teams to sniff and we know him best. Hard NO. Besides, Rasheed Walker played pretty well last season. I haven't seen or heard anything from camp that indicates otherwise.
