I'm with StoneCold and MontanaHawk. This is Peter King making up BS as clickbait.
RG3 has been beaten out by Kirk Cousins (and possibly even Colt McCoy).
IF RGIII gets released by the 'Skins... I would expect to see him clear waivers, because I don't see teams claiming him and risking being on the hook for a $16 mil cap hit next year. If I'm understanding it correctly, he's $3.3M this season, BUT, if injured, $16M next season, and the chance of him getting reinjured seems a bit high. If the question was simply this year, different answer. Someone please chime in with how it actually works if this is an incorrect translation.
As far as NFL QBs and leadership, he's been a bust in that area after his injury.
Pete did kick the tires on Terrelle Pryor at QB, and ultimately, release him; he never seemed interested in Tebow. I think the issue would be RGIII's willingness/ability to have the humility to go back to the basics and rebuild his whole foundation as a QB, this time without assuming his (apparently no longer present) "Superman" athletic ability can bail him out of anything.
I do find myself rooting for TPryor to make a go of it at WR in Cleveland.
