Sturm has been very level headed when it comes to Dak. He initially thought Romo should have gotten his job back. But as weeks have passed he changed his mind.
Dak has to be considered the best pick in NFL history, based on just his rookie season of course. Nobody knows what the future holds.
538 pointed out before the season opener just how rare it is to start a rookie quarterback who was selected so low in the draft like Dak was with the 135th pick.
"You have to go all the way back to 1977 to find a quarterback not selected in the first 130 picks of the NFL draft who then went on start his team’s season opener as a rookie.
That player was
Randy Hedberg, who started for the terrible Buccaneers franchise in 1977. Hedberg is one of the worst quarterbacks in NFL history — he finished his career with a 0.0 passer rating. And, to date, he is the only quarterback since the merger in 1970 to be drafted outside of the top 130 picks and then start in his team’s season opener just a few months later."
