None of those guys is really a highly rated prospect. I think the Bears (and their GM) were desperate. I think they would take what they could get from any team and not be picky.
Trubisky had 1 year as a starter. If he had 2-3 years as a starter with 2 very good years then I’d consider him a better prospect.

Andrew Luck could have been pick. If Sam Darnold has another very good year, he could be picky.

Using this year as an example – where do you think Mitch Trubisky, Pat Mahomes and Deshaun Watson might have ended up to avoid being on a bad team, and do you think that would have been less money for them?
