People aren't trading a young starting 10-15 sack a year OLB in May and June. That shipped has sailed. If you move Mo, it will be for future picks and leave the roster with less talent in 2015.
If we trade Mo, Williams better be a stud, because if he isn't and we trade Mo, he may be on a similar path to Idzik. mac better handle this situation right. Losing our best player and drafting his replacement didn't work out too well for Idzik...Revis for Milliner. careful history doesn't repeat itself.
That's why you keep Mo now, and utilize the franchise possibility. If Williams becomes a stud, then you can deal Mo if you want. But if you control him this year, and still have two franchise year options ahead, why rush it?
