Editor's update: Brandon Shell was incorrectly listed a free-agent tackle as he was signed to the Miami Dolphins practice squad last week. The Chargers could poach Shell from the practice squad, as long as the Dolphins don't name him one of the four protected players this week.
3. Brandon Shell
Most of the options on the market would not be that much of an improvement over Norton, regardless of how bad he has been. Most of the options have very similar efficiency numbers as Norton and would just be throwing a band-aid on a wound. Brandon Shell is one of the few players that does have better results at right tackle.
Granted, the results are not that much better but the team would still be making an improvement. Shell has spent his entire career at the right tackle position and has not been great but has had moments where he has held his own in the league.
Over the last two seasons, Shell's efficiency rates have been 96.4% and 97.5%, both of which are better than Norton's best season. Outside of a down year in 2019 with the New York Jets, the fifth-round pick has always been better than Norton.
In fact, there have been moments where Shell looked legitimately fantastic. In 202 pass-blocking snaps in his rookie season, he did not allow a single pressure. Chargers fans should not expect anything that special, but the potential is there.
Outside of these three options, the Chargers would just be making marginal upgrades at best. Sure, they could take a risk on a Bryan Bulaga reunion of sign someone with similar numbers but if the team truly wants to make an improvement over Norton, these three options are the way to go.
