Agree that they already had an extremely slim chance of winning once Purdy got hurt, but going to halftime only down by 7 is a lot different than going down by 14. No question that Johnson sucked. Worse than a HS quarterback, I have no idea what he even did these past 10 years in the league. But going two-minute no huddle offense with him is all on Shanahan.
And Purdy may not even get injured if he challenged that first call. Philly rushing to the line and calling a no-huddle offense after a 40 yard reception? As a coach, how do you not suspect something is up.
