There could be some parallels between SF and IND...and perhaps some lessons. (Look at who started that following season for SF).
SF needed a franchise QB back in 2017. But even though SF ultimately had the #3 pick...they passed on drafting a QB like Mahomes or Watson. Instead, they grabbed a developmental QB prospect in the 3rd round. They then used that pick on a "blue chip" DL player.
Fortunately...they were able to trade for Jimmy G that following season. Maybe they knew they would eventually land Jimmy G...or could get Cousins the following year in FA...but it was risky to pass on drafting a QB.
The Colts need a franchise QB. They don't have the #3 pick...but they are in a position to realistically to get one of the top 3-4 guys. And this is where the Colts are faced with a similar choice. Do they grab their guy at #13 (or perhaps move up a few spots)...or do they pass on drafting a QB early like SF did...and grab a developmental QB in rounds 2-3...while working toward a more proven option...perhaps a Derek Carr trade.
IMO...they are drafting somebody...either as the long-term franchise QB, the developmental backup for the foreseeable future (even if they do manage to get a proven upgrade prior to the draft) OR as a hedge for a future move.
It worked out for SF in the end...but Beathard got beat out by an UDFA and Thomas has been a disappointment.
Going to be very interesting to see how Ballard plays this. I know what I would do...but that's about it.
