Treylon Burks - Former first round draft pick who Andrew Berry has previously been linked to makes a lot of sense as a player they could target and battle to try and make the 53 man roster. He might try and target a team with a more proven answer at quarterback though.
Alec Pierce & Romeo Doubs - I can see these both as players that the Cleveland Browns would be interested in, the issue could be them not wanting to go to a team with uncertainty at quarterback and on the offensive line.
It will be interesting to see if Shedeur Sanders' celebrity status can be used to attract talent to the team. I can see them looking hard at the trade market for this position as they have done in previous years as you know what you have heading into free agency rather than the risk of ending up without a player you want. I don't tend to write on potential trade targets but I might do this at quarterback and wide receiver.
