Mike Tanier covers the NFL for Bleacher Report.
this is excerpted from his report:

.......If Bradford wants to restore his reputation, and more importantly his marketability/trade value, he needs to follow the following five steps:

1. Own the last three weeks: Bradford should not try to play off the trade request and holdout as some kind of "misunderstanding," and he cannot let the perception that this was an extended hissy fit linger.

The "business side of football" part of Bradford's official statement is the first step toward setting the proper tone and spinning his trade demands in the best possible way. He saw the Eagles trade up for Wentz and wanted a chance to compete elsewhere. When a draft-day trade failed to materialize, he held out for a few days as leverage to force a trade. But now he's here, he hasn't missed much and he's eager to prove what sort of competitor he really is and always has been.

In other words, it was all just business, nothing petulant.

2. Extend the olive branch to Wentz: Carson Wentz can be Sam Bradford's greatest advocate in the weeks to come. If Wentz raves about Bradford's advice and guidance and speaks fondly about the atmosphere in the meeting room, it will mean more than anything Bradford or his coaches can say on his behalf.

Bradford has a lot of 'splaining to do in the upcoming weeks: to Pederson and the coaches, to teammates, to owner Jeffrey Lurie and just about everyone at the NovaCare Complex. But Bradford must prove himself as both a competitor and mentor to Wentz, a fairly common dual role for a veteran-journeyman quarterback. If the quarterback competition in Philly devolves into Bradford vs. Wentz: Dawn of Controversy, the blame for any unnecessary intrigue will fall on the guy who kicked the Wentz era off with a tantrum.

3. Squelch the retirement talk (hard!): Bradford considered retirement after tearing his ACL for a second time in August 2014, according to Mike Sielski of the Philadelphia Inquirer. However, Oklahoma assistant coach Josh Heupel talked him out of it, and Bradford rehabbed the knee before the Eagles trade. The recent retirement talk was just speculation and scuttlebutt, but there's just a little too much retirement talk around Bradford.

No one would blame a player who suffered as many injuries (and has as much money in the bank) as Bradford if he chose to retire. But no one really wants to trade for or sign a player who sounds like he is one reversal of fortune away from quitting, either.

If Bradford really plans to claw and scratch to keep pursuing his NFL career, he must make that clear by denouncing the recent retirement rumors as vehemently as possible.

4. Follow the Alex Smith template: Alex Smith should be Bradford's role model for how to handle the 2016 season. Like Bradford, Smith was a first overall pick. Like Bradford, Smith spent five years in career limbo. Just as Smith appeared to establish himself as an effective starter, his organization became enamored with Colin Kaepernick, just as the Eagles now covet Wentz.

Smith did not give way to Kaepernick without a fight in 2012, but it was an on-field battleŚnot a war of trade demands and holdouts. Smith was in demand after the 2012 season, the Chiefs dealt a bunch of draft picks to acquire him, and after signing a four-year, $68 million contract extension, Smith has embarked on a second career as a sturdy, playoff-caliber game manager.

Smith represents the best-case scenario for Bradford, who must prove he can hold off Wentz for a few weeks or months to start the season. If he can do that, quarterback-hungry suitors will emerge for a veteran with moxie. If he cannot hold off Wentz, well, nothing else really matters, does it?

5. Adopt an attitude of gratitude. Bradford refused to allow the Rams to rework the six-year, $86 million contract he signed in the wacky days before the rookie salary cap, per Andrew Brandt of The MMQB, despite the fact that he missed two full seasons with ACL injuries. Bradford reportedly turned down a four-year, $72 million extension from the Eagles last autumn, according to 94WIP's Howard Eskin (via CBS Philly's Ray Boyd). Now, he's shown that $22 million in guaranteed money doesn't buy enough loyalty to get you to Mother's Day without intrigue.

You can claim to be #blessed as often as you like, but when your actions make you look like the George Clooney character from Money Monster, the guys who set the budgets and write the checks will notice.

If all of the financial hardball of recent years is Condon's doing, Bradford must make it clear that Condon works for him, not vice versa, and that he will no longer let money be an obstacle to his competitive goals. At the very least, Bradford must handle himself more like a man who knows how lucky he is to still command eight-figure salaries, not a guy on an endless redshirt scholarship.

Bradford went from gallant to goofus in just a few weeks. It will take months or years to undo the damage. A winning season will turn everything that happened since the Wentz trade into a footnote. But unless Bradford gets control of his story and his reputation, a winning season will be almost impossible, because no one will be eager to give him the chance to have one.
