It wouldnt matter.
Unitas would play one game against a Patrick willis or Troy Polamalu and beg for mercy
Ridiculous. If Blaine Gabbert can play QB in today's NFL, so could Johnny U. You make it sound like he was playing alongside freaking Sammy Baugh. You realize Unitas played in the Super Bowl era right? Should we just discount every player and team from, say, the first 5 or 6 super bowls because the level of physicality has evolved? Should we just erase those first several seasons off the record books?
