I believe that Suh on our defense would bring the something that Sammy Watkins brought to our offense, there is so much that Suh would bring that it would be hard to quantify in just sacks and pressures. Suh along with Donald would be the greatest DT tandem ever in the NFL. By establishing the type of pressure "up the middle" you have to account for them with other people. You can not double team them with a tackle, you have to have your center and a RB (thereby taking a ball carrier or potential target out of the game plan). Normally the defense is considered to have on extra guy unless you have a Vick like QB.
So our defense has already dictated that you have to account for two of our guys with four of yours, and you are using one of you playmaker options to account for our inside presence. Remember we still have Brokers and two edge rushers that you have to account for. We are going to force teams into a double tight or quick hitting play offense, there will be no slow long developing plays and you are basically playing Russian roulette if you do play action because of the amount of time you hang on to the ball behind the line of scrimmage. Not to mention we have two great cover corners that will allow our LB's and edge rushers to cheat or gamble (blitz) to me I see the pressure and the suffocation of offenses that the 85 Bears had with the signing of Suh.
