Jon Baldwin watched from the other sideline Friday night as Colin Kaepernick zipped warm-up passes to his wide receivers, then Baldwin marveled with a couple of Kansas City teammates about the 49ers quarterback.
Fast forward four days and, by lunchtime Tuesday, Baldwin had already caught 15 balls from Kaepernick for his new team. San Francisco acquired Baldwin from the Chiefs on Monday for fellow underachieving former first-round draft pick A.J. Jenkins.
Baldwin passed his physical late Monday then went to work at 7 a.m. Tuesday with meetings and practice. He quickly made it a point to meet Anquan Boldin, someone Baldwin knows will be a valuable resource as he quickly tries to grasp yet a fourth offense in three years.
