This is exactly how I'm feeling right now. As FA approaches, I'm becoming more and more pro-Cam. For several reasons as you've stated above.
I'd much rather Cam come in knowing the system, knowing the coaches rather than an adjustment period with someone like Mariotta, Darnold or Fitz. Not to mention the draft capital it would take to acquire them.
Sign Cam and go heavy adding weapons for him at WR, OL and TE. Would love to see them add both Robinson and Samuel if they could.
If Ron, Turner and company want to bring him in to start, I trust the process. No one knows him better.
