Is a Fields trade realistic? Diontae Johnson's future, Broderick Jones at left or right tackle

Hour 1 with Dorin Dickerson, Adam Crowley, and Paul Zeise: Steelers insider Gerry Dulac went on The Rich Eisen Show and said if Justin Fields was on the board when the Steelers picked, they would have taken him over any other player. Crowley doesn't think they know how to evaluate quarterbacks and it seems they would pick Fields over Trevor Lawrence if they had the first pick. Crowley feels worse about the situation and the fact that they can't evaluate QBs. Ranking the AFC quarterbacks. 11 teams have a QB we know will start week 1. The Steelers are with the Broncos, Patriots, and Raiders with complete uncertainty at quarterback. Steelers insider Ray Fittipaldo doesn't see another extension being talked about with Diontae Johnson. Crowley wouldn't be surprised to see the Steelers pick a WR in the second or third draft, but Dorin thinks they should find a veteran receiver. Fittipaldo thinks Broderick Jones could easily be the right tackle again next season. He seemed to be the left tackle of the future. Does this mean the Steelers take another left tackle?
