In my opinion, it is the correct call. The numbers were quoted in the article for a direct comparison as
Russell completed 10 of 16 passes against Oklahoma State. Prescott finished the game 7 of 17 for 89 yards. The sophomore followed it up completing 12 of 19 passes for 174 yards and two scores against Alcorn State, an FCS opponent who went 4-7 last year.
Against the same defense, Russell completed more passes for more yards and the offense had several decent drives in the first half before stalling due to mental errors, dropped passes and questionable offensive play calling. Russell has earned his spot, but I think there is a lot of room for enthusiasm for Dak as his future looks very bright with MSU.
As noted, our problem lies in our inability to control the line of scrimmage on offense and defense. When we do, then we are a good football team. When we don't, then we aren't very good. Frankly, despite our blowout of ASU, I was still very disappointed in only recording 1 sack in a game where they were forced to throw the ball alot. Our DBs did a good job for the most part, and we got a little pressure with 4-5 hurries, but our DL needs step up as well as the OL noted in by the previous posters.
