Kliff has done so much with an offense that is still talent deficient at several spots along the OL, WR, and to a lesser extent, RB.
Washington has money to burn this coming off season, and a solid collection of draft picks this coming April. There are ample opportunities to strengthen the overall quality of the offensive group. A part of Kliff has to be thinking that it would be pretty enticing to pair a 2nd year Daniels with that.
There certainly is the possibility that Kingsbury can get this offense to reach even higher levels and that can help him command even more money on the open market in another year if he stays patient for a bit.
It's risky, because from year to year, things can change quite quickly in the NFL, but the eventual payoff could be huge for Kingsbury.
