Yes he is.
If Alex Smith is your floor, you are 100% a franchise QB.
Also I dont see the parallels between Smith and Dak. Smith in his first two seasons had a completion % of 56%, 17 TDs to 27 INTs, 6.1 yards per attempt, with roughly a 65 QB rating.
Dak has a 65.2% completion %, 45 TDs to 17 INTs, 7.4 yards per attempt, with a 95.5 QB rating.
I dont see the resemblance.
Although the Wilson comparison is much better!
63.6 completion %, 52 TDs to 19 INTs, 8.05 yards per attempt, and a 100.6 QB rating. So that's much closer.
Many here would have given up on Wilson after his first two seasons. It's pretty sad.
