The Chargers' one glaring miss is edge rusher, a need they left exactly as they found it. Some smart calls, some head-scratchers, and a C+ in the wash.
Ioane has a lot of ground to make up just to look fairly priced. On the needs board they went 1 of 8, with offensive lineman the one that mattered most.
Building through the lines is a philosophy, and they stuck to it.
If Olaivavega Ioane and a couple of the gambles land, hindsight will be kinder than this grade.
