Here's the thing, Geno has a big cap number for this upcoming season, $44,500,000, and the team is under water in relation to the cap by almost $27,500,000. Geno is a very capable QB but truly has limits to his upside. I suspect he's likely done here despite his middle to slightly above average ability. I would suspect in terms of cost to benefit he's just too expensive and eating a dead cap hit of $13,500.000 to realize a cap savings of $31,000,000 will be preferable to the team than eating a cap hit of 44,500,000. Next up is Howell who is under contract for next season already and his cap hit is factored in already.
I have otherwise elsewhere negatively commented upon Gee-NO and perhaps am biased but I think the team could use his cap money and some other significant savings to improve for next season. There are few obvious candidates for renegotiation or release that could provide the cap needed for a few critical signings like Jones or a quality LG. Smith has been a temporary solution for his position and despite his redzone woes has been a reasonable but unspecial bridge to a new regime. I'd expect him to be released or possibly traded because he is just not worth being paid $44,500,000.
I guess time alone will tell.
