I don't claim to have any inside info on the Maybin negotiations, but an analysis of the numbers can help explain the impasse.
A lot of the blame for Maybin's contract holdout has gone to Michael Crabtree's holdout one slot ahead. However, the real sticking point is Knowshon Moreno's 5 yr $23 million ($13 million guaranteed) one spot behind. Maybin's agent wants more than Moreno. Based on Raji's numbers, I'm guessing Maybin's agent Joel Segal is asking for 5 years, $25 million, $15 million guaranteed.
Consider picks 9-13
9 Raji 5yr $28.5 million, $18 million guaranteed
10 Crabtree - not signed
11 Maybin - not signed
12 Moreno - 5 yr $23 million, $13 million guaranteed
13 Orakpo - 5 yr $20 million, $12 million guaranteed

The Bills are using last year's numbers to inform their negotiations.
9 Rivers 6years, $23 million, $15.6 guaranteed
10 Mayo 5 years, $19 million, $13.8 million guaranteed
11 McKelvin 5 years, 19.4 million, $12.6 million guaranteed
12 Clady 5 years, $17.5 million, $11.5 million guaranteed
13 Stewart 5 years, $20 million, $10.8 million guaranteed

The Bills are pointing to RB Jonathan Stewart getting a larger contract 2 picks behind McKelvin.
The Bills are probably offering 5 years, $22 million, $13 million guaranteed.
The Bills can't justify paying 25% more on this year's pick as they did on last year's pick in the same spot.
I'm guessing a deal gets done at $23.5 million, $13.5 million guaranteed.
