2014 they had two pro bowlers on the OlineWho can he throw to? On top of that he had the league's worst line. Dude had his limitations but you don't just fall off like that. 9ers fell off considerably. There were many factors including Kaeps regression.
Boldin had 2 1000 yard seasons and Crabs had one. Those were his #1 receivers
2015 they had one
their line was NOT the worst in the league especially in a league that contained the Dolphins Oline and the Jaguars lol
2015 was definitely a down year for the whole team. ANd they lost some weapons and key elements on both sides of the ball. but dudes were saying this guy was ELITE, an elite player doesn't drop to bottom third losing a few players.
the league figured him out for the most part. All they had to do was contain him. and he was more or less a one trick pony and was figured out, He just can throw accurate enough to stand in the pocket and hit receivers consistently THAT is and has always been his problem.

The offense was up and down with Alex but with Kap the zone read was a game changer for the 49ers that season
