Wow, you really need to read up on the facts.  CK was average, sometimes great, sometimes awful.  But he was, and is, in the top half of starting NFL QBs.  That's just a fact.

He never had "outrageous salary demands".  I assume you fell for the widely debunked story about CK opting out of his last year in SF "because he wanted to get paid more".  The truth is, and EVERYONE in football circles knows this, the 49ers already had plans to cut him, which they told him about.  He knew he wasn't going to get cut, the 49ers knew, his agent knew, everyone knew.  So CK simply opted out, and became a free agent, so he could try to catch onto a team sooner.  But the lame (mostly in conservative circles, no surprise) talking point became "CK opted out of a 17 million dollar deal because he wanted more!".  A complete fabrication.  lol
