Sometimes the craziest ideas end up making the most sense.

Trade possibilities now have been mentioned with two of the NFL's most successful quarterbacks in the San Francisco 49ers' Colin Kaepernick and the Seattle Seahawks' Russell Wilson.

Putting Russell Wilson on trading block an option for the Seattle Seahawks?

The 49ers apparently are worried that Kaepernick's 2014 season is a trend, not an aberration. His 2015 season, after all his offseason work with former two-time NFL MVP Kurt Warner and quarterbacks coach Dennis Gile, will be critical to his future with the team.

Kaepernick guided San Francisco to three consecutive NFC Championship Game appearances from 2011-13 - and a Super Bowl XLVII appearance - prior to the team's dysfunctional, 8-8 season in 2014.

San Francisco to consider trading Colin Kaepernick to reload?

ESPN's John Clayton reported that the 49ers' best days with Kaepernick are behind them and the best day to reload is to break clean from their quarterback

Wilson arguably has been the biggest NFL bargain since he entered the league in 2012. He has directed the Seahawks to back-to-back Super Bowl appearances, winning Super Bowl XLVIII.

But Wilson wants to be the highest-paid quarterback, and the Seahawks are looking at the Baltimore Ravens, who made Joe Flacco one of the league's highest-paid QBs after he led the Ravens to Super Bowl XLVII win over the Niners and have not been back to the Super Bowl since.

What if the division rivals simply swapped QBs?

The advantages for the Seahawks would be obvious. With the team-friendly deal Kaepernick signed, his cap number would be lower to Seattle than that of Wilson if the Seahawks give him a contract similar to that of Green Bay Packers' quarterback Aaron Rodgers' $22 million annual salary.

For the 49ers, Wilson would be a bit pricier now, but the team has newfound cap space with the rash of recent retirements by Patrick Willis, Justin Smith, Chris Borland and Anthony Davis. Unlike Kaepernick, Wilson has not yet had a season in he has regressed.

If he could lead the 49ers back into the playoffs, the team would get relief in future years when the league salary cap increases. Plus, Wilson couldn't hold the loyalty card against the 49ers the way he seems to be doing against the Seahawks for taking advantage of his rookie pay scale.

If Wilson isn't able to elevate the 49ers, they could ask him to renegotiate without as much fear of resentment from him.

As members of one of the most heated rivalries currently in the NFL, don't expect either side to be making inquiries anytime soon. That would be crazy, right?

But if both situations worsen, don't think that at least one side wouldn't at least think about it.
