In the ever-shifting realities of NFL free agency, anything is possible.

The longer goofball Howie Boy Roseman waits to re-sign Eagles quarterback Sam Bradford, the less Bradford feels wanted.

And that leads to rampant speculation:

When Colin Kaepernick’s agents let it out that their client would like a trade from the San Francisco 49ers, Sam Bradford’s name popped up as a possible replacement.

A year ago Chip Kelly liked Bradford enough that he sent quarterback Nick Foles and a second-round pick to the Rams for him. So as a free agent Bradford heading to the quarterback-needy 49ers, sans Kaepernick, would make sense.

Except for a few important factors.

Kelly is not running the Niners’ personnel department. That role is filled by general manager Trent Baalke, who has been hesitant to acquire high-profile quarterbacks through free agency.

The 49ers’ way, going back even before Baalke has been to draft quarterbacks. It’s how they acquired Kaepernick. With the No. 7 overall pick in the first round, if the 49ers want to draft a quarterback again, there will be one there for them.

Chances are if Kelly were still the Eagles’ head coach, a deal might have already been in place for Bradford. The question is does Kelly, after just over a month on the job, have the juice to convince his boss a quarterback, who has never had a winning record in six years, is worth what it’s going to cost to sign him?
