If the Chiefs’ return for Marcus Peters seemed underwhelming, that’s because there was not a booming market for the cornerback’s services. The Browns and Colts were never major players for Peters, according to Ian Rapoport of NFL.com (Twitter link), despite both teams having execs that were involved in drafting him. 
Shortly after Peters was shipped to the Rams, there were conflicting reports regarding the Browns’ involvement. It seems that we have a better understanding of Cleveland’s participation now – the Browns explored a possible Peters deal, but they were never serious suitors.
The Colts, meanwhile, will be on the lookout for a cornerback, particularly if they do not re-sign Rashaan Melvin. However, they are armed with $74MM+ in cap space and are near the top of the draft order this year, so they have other ways to bolster the CB group. Peters would have given the Colts a top-end starter in the secondary, but he may come with headaches and the price to get him was apparently still too steep for GM Chris Ballard‘s liking.
On Monday afternoon, we learned that the Rams are sending a 2018 fourth-round pick (No. 124 overall) and a 2019 second-rounder to the Chiefs in exchange for Peters and KC’s sixth-round choice (No. 196). That’s probably less than the Chiefs expected to receive, but they did not like the odds of getting Peters’ behavior under control and were uncomfortable with the prospect of giving him major dollars beyond his 2019 option.
Expensive showboating cornerbacks (Aqib Talib, Marcus Peters, to a lesser extent Richard Sherman, Josh Norman) and wide receivers (Des Bryant, Odell Beckham Jr) seem to be a real source of headaches and controversy for NFL coaches and managers these days. No wonder few wanted to trade much much for such a troublemaker.
There’s quite a few elite players not playing at all these days, pricing and nuisancing themselves out of the league (Colin Kaepernick, RGIII). I still can’t believe Kaepernick let his girlfriend sass Baltimore’s owner when Steve Biscotti was the only one in the league still willing to give him a chance. Even to a Kaepernick fan and a BLM sympathiser, it seems like a colossally stupid move.
It looks like the no strings attached contract for potential stars died when Johnny Football Manziel blew out of the league in two years.
If you honestly think Kaep and RG3 are “elite” players, you need to put down the pipe and sober up
RGIII = Rookie of the Year 2012, Pro Bowl (not to mention Heisman 2011 but that’s college)
RGIII never fully recovered from his knee injury in the 2013 wild card match against San Francisco, neither physically nor psychologically.
Colin Kaepernick beat out Alex Smith, yes that Alex Smith who led the NFL in quarterback rating in 2017 for the starter job on the 49ers not once but twice. Colin Kaepernick who rushed for 5 touchdowns in 2012, enjoys a 72 touchdowns to 30 interceptions career stat and led his team to Super Bowl XLVII.
Kaepernick is the only quarterback in the history of Division I-A college football to have passed for over 10,000 yards and rushed for over 4,000 yards in a collegiate career.
That’s elite enough for me.

Oh man, that was a stupid move by the girlfriend. One person was willing to sign him and she spits in his face.
