Sure if it costs nothing jettison white but Skylar is number 2 lance can run the practice squad
For now. I wouldn't advocate getting Lance to run the practice squad, but if you think he eventually can be your backup, I think that's a smart move.
By the way I watched the highlights of that Dallas game and he did a lot of good along with those 5 picks. I think like 3 of them were in the last quarter when they were trying to make a comeback with the last one on the last play of the game where he forced it into the endzone. On another one he hit the receiver in the hands but a little high and he juggled it a little and the defender took it away so not really his fault on that throw either. Still that's 3 picks in a game where he threw almost 50 passes, but he's young and hasn't played much. I would expect that to get better the more he plays. The good throws in that game were pretty impressive.
Now would be a good time to offer the Cowboys something for him. He probably wouldn't be ready to play this year much unless Tua goes down, but I wouldn't mind seeing him compete with Thompson for the backup. He's a major upgrade over Mike White, that's for damn sure.
