49ers' Trent Baalke: Colin Kaepernick, Reggie Bush 'developing a real rapport'

Reggie Bush was mostly an afterthought during his final season in Detroit, but the running back is already catching the attention of San Francisco 49ers general manager Trent Baalke.

Baalke said he believes the pairing of Bush and quarterback Colin Kaepernick will be good for both players, during an appearance on SiriusXM NFL Radio on Tuesday

"Reggie has really been an asset to Colin and has opened up some things," Baalke said, according to Matt Maiocco of CSNBayArea.com. "When you get the speed going down the field and you give a back like Reggie room to work in the third-down packages and stuff like that, it really is a bonus for the quarterback.

"And Colin is developing a real rapport with Reggie coming out of the backfield.”

49ers head coach Jim Tomasula told reporters in March he believes Bush can play a significant role for the team in 2015, and while it's still early, Baalke's observations lend support to that.
