SANTA CLARA As Kyle Shanahan said (in so many words) earlier this year: The spring is for learning the playbook, the summer is where the roster jockeying begins. With that in mind, here's how the depth chart looked when the spring sessions ended as well as some of the storylines to come when training camp gets underway. Players report on Thursday; the first practice is Friday.
Next up: tight end
TE1: Vance McDonald, Blake Bell, Cole Hikutini
TE2: Logan Paulsen, Garrett Celek, George Kittle
Storylines:
* McDonald is the most athletically gifted tight end on the team but either through frequent drops or frequent injuries hasn't been reliable.
