An interesting side of this argument is having a 'franchise QB' isn't a cakewalk. There are ups and downs. For the past 10 years some in NE have been talking from moving on from Tom and many applauded the move. Many were calling to move on from Elway, Manning, Montana and Mario the later they got into their careers and there are some ups and downs along the way.
Here's what I'm asking: if you did a Cutler type trade, but ended up with a slightly better Cutler experience is that still a win? If Watson comes here and he's a perennial top 10 QB, but you guys don't win a championship is that still considered a win?
For my Eagles while I've been a fan we've had three 'franchise QBs', being Cunningham, McNabb and Wentz. All ended with varying levels of frustration and there were definitely lows with the highs.
Think about the Texans fans. Do you think Watson has been great in every game while the team has failed this poorly? No. He's got areas to get better and trading a lot for him won't fix your current problem AND solve all his play issues. You'll be better, but you'll also still have some shit to cunt about.
Truth be told, a lot of this Watson situation is eerily similar to Cutler. Pre-Chicago he wasn't regarded as a douchbag. He really earned that reputation in Chicago. Thinking of Cutler pre-trade he was a 25 year old, extremely physically talented QB who had issues with management/coaching. He forced his way out of town. Watson is also a 25 year old, extremely physically talented QB who has issues with management and is forcing his way out of town.
Really take a step back, look at what the league thought of Cutler back then and extrapolate that to the potential Watson move. Like I said, it's eerily similar.
