BW,
I do not know what your football background is, but man...I think you need to brush up on the fundamentals:
1. 265-270 is too light for a 5 tech DE. <FULL STOP> He will get destroyed at the point of attack with a guard and a tackle double teaming him.
2. You better hope if we use Bosa at a DE that we are playing one gap, if we play two-gap, that means the expectation of the DE is to engage the OT, and control the gaps to his left and right (B & C)...a two gap NEVER rushes up field...all of Bosa's rushing skill is wasted...I cannot think of a modern NFL team that runs a two gap scheme.
3. Yes, Bosa could play a 7 or 9 tech DE with his hand on the ground...but that is not the base defense.
4. Bosa will be an OLB in our scheme, just like Jones, Suggs, and Reed.
5. Bosa (or any of the OLBs) can be moved inside on obvious pass plays when a nickel or dime package is on the field...But he is an OLB.
I agree, VJ has indicated that we will use an aggressive D and we have some nic wase pieces to add with Bosa that will give us an unrelenting D, with a ton of depth.
