The premise was flawed IMO, Kuehnja, because you started with a blanket subjective statement to start your argument that was inherently flawed in terms of the questions you say you were trying to pose.
We are slow? Slower than teams that throw out, like Purdue, lower ranked kids according to recruiting services? I'd like to know what percentage of our team you honestly think is slower.
Are our ILBs slower than most WRs, RBs and TEs we face, yes. Probably ditto for our safeties we are starting right now. Who else is slow, to the point of having to debate firing a well respected S&C coach? Further, for one who has harped on the 'poor angles' our tacklers take a good amount of the time, how much do you think that has to do with a perceived lack of speed while watching in the heat of the moment?
Certainly not our WRs, who have proven to be as deep and explosive a unit as we have had in long, long time.
Not our RBs, with a possible exception of Cam, who displays other traits that make him valuable to the team besides straight speed.
TEs? Pretty sure I remember seeing Niklas out run the secondary of Temple in week one for an impressive score.
OLBs? Shembo, Councell and Jaylon all move extremely well, especially Jaylon. Ishaq has good straight line speed for his size, but has limited horizontal abilities (which is why I disagree with the way he is being used, but that's another argument)
CBs? Both Bennett and Russell run well, as evidenced by them both running with Lee last year in deep routes step for step. Do they have shortcomings in other areas, yeah, but they both undoubtedly have the athleticism and speed to play the position.
