A few points....
You do realize that 3 of our top 5 LBS didn't play on Saturday right? Dunno what the DC can do about injuries.
How many 3 and outs have we had over the past 3 years? How do you think those affect defensive stats? Here's a hint....not well.
Do you expect Purdue to have a lock down D? If so, you're nuts. Go cheer for Alabama.
I think Hudson has done a DECENT job with the D. Sure, there are many shortcomings. That said, i'm not convinced that if you let him go Purdue is going to go hire somebody better. COULD they? For sure. Will they? Again, not convinced.
That said, John Shoop has been beyond abysmal in his tenure here and I think the D #s would look a whole lot better for Hudson had shoop NOT been here!
There is no question that Shoop's offenses have put Hudson's defenses in some bad positions in many games. Still, it is obvious to most people that Hudson's schemes are deficient.
You do realize that Purdue ranks in FBS this season:
104/128 in scoring defense 34.3 ppg
104/128 in total defense 436 ypg
92/128 in passing defense 252 ypg
90/128 in rush defense 184 ypg
2014
98/128 in scoring defense 31.7 ppg
85/128 in total defense 416 ypg
58/128 in passing defense 222 ypg
96/128 in rush defense 194 ypg
2013
114/126 in scoring defense 38.0 ppg
106/126 in total defense 460 ypg
55/126 in passing defense 225 ypg
117/126 in rush defense 235 ypg
Under Hudson, our defenses are not mediocre. They are flat out bad. You cannot lay this all at Shoop's feet, although he certainly hasn't helped matters.
