If Sweat can keep up the consistency at or near the tear he's been on since getting to Chicago, then he's flirting with All-Pro. Now, will he come back and do this next year and beyond, who knows. They paid him like he will.
But with already paying Allen and Payne, to sink another top dollar contract was probably unreasonable. They were never gonna do 4 out of 4, but even 3 out of 4 on the DL getting paid was gonna be tough to manage.
