49ers according to PFT have $105.9M committed to the top 51, this likely includes Spillman's extension, but not Brooks' extenson.
I have the team at $111,812,576M, but that includes Brock, Tukuafu and Grant expected tenders, plus Goldson's expected franchise tag and projected Spillman's extension figure. If I take away those figures I'm left with $103.625.576M, that includes a $1.048.294M in dead money. If numbers are correct and as close as possible I'm off by $2.274.424M, but there is no way that is devoted to Spillman, it likely has to do with some unknown escalators or bonuses I've overlooked.
I have Spillman at around $1.215M, so that would, if correct or close, leave us at a difference of $1.059.424M.
