I really don’t know why you’re so hell-bent on being the Andrew Luck-Colts.
I have a LT. It is a deep draft class for OL, especially C. I feel like I can add picks by trading some or all of Hopkins, Kyler and Brown. At worst I am adding 2nd and 3rd rounders. I can fill a hole on the OL in FA without Kyler's contract long term...either Jawaan Taylor or Conner McGovern or Dalton Riser. I might be able to bring back Will Hernandez who was fine.
I can add a RB easy especially if I am going to be run dominant on offense.
Defensively the HC would need to figure out what works with the new scheme and then add bodies as they are avaiable.
The Colts failed because of their GM. We are counting on not having that problem.
