Assuming the Chargers get Tua at No. 3, what about No. 37 in the second round? If Trevon Diggs slides to the second round, as he likely will, his speed and size give him too much upside to miss.
If Diggs is not available, taking an offensive tackle would be a better option. The Chargers will need to stiffen the line, especially in pass protection. Unless Isaiah Wilson slides out of the first round, either Austin Jackson or Josh Jones is the pick at No. 37.
After trading away No. 71, next up for the Chargers early in the fourth round, will be No. 112. Assuming Diggs at No. 37, the Chargers need to address offensive line help. Auburn’s Prince Tega Wanogho would be the pick but is likely taken higher. Missouri’s Yasir Durant is a good option. Some fans would prefer Ezra Cleveland. But a competent, former SEC lineman, who has history battling athletically superior players, is better than one who faced Boise State’s competition.
Another offensive line option would be to go for a center. There is no assurance Mike Pouncey will be cleared medically to play football again. Wisconsin’s Tyler Biadasz meets that potential need in 2020 or beyond. Depending on the inside information on Pouncey, adding Biadasz might be more important than adding a tackle.
If pick No. 37 went to an offensive lineman, a cornerback will be needed at No. 112. Tulsa’s Reggie Robinson would be a good choice. He has the size and speed need to become a solid NFL corner.
