There are so many needs it could be just about any defensive position. A 1T is certainly at or near the top of the list, I've felt we needed one for years. But it could also be a MLB, or a true safety, be it SS or FS. Sean Lee may have only a year or 2 left, might need to consider that. Scandrick makes a big play here & there then disappears & our other corners aren't stopping anybody at all. We might be OK at DE but even at that what do we have other than Dlaw? Things might not get better without a huge infusion of defensive talent, more than you're likely to get under the current FO mindset. And then there's the defensive coach & scheme, that's a whole other issue.
And it's not like we're without offensive needs. The oline has taken a definite step backwards. We have to consider WRs & TE.
How did things go so bad so fast?
