Chris Brockman on the Rich Eisen show somewhat recently said he thinks Zach Wilson may be in the UFL next season. That would be something if he can't even make an NFL practice squad.
Speaking of the UFL, one QB the Chargers need to look closer at is Luis Perez. He was on the Rams 5+ years ago, but only in the preseason. He's since played for the XFL, AAF, USFL and now UFL, putting up impressive numbers, even on weak teams, winning the XFL championship even. So much so his nickname is The King of Spring. He's bland, but quite intelligent when you listen to him. Because the UFL mic'd up the QBs you could often hear conversations with coaches, or before plays, and he had more command on his team's offense than any other player.
I'm also curious if what Harbaugh said about Kaepernick is really true. In the last several years only one team even gave Kap a workout (Raiders). Kap is still just 36. Why not let him try out? Then if he really is too old, then talk about him being a coach. I think what's bothered me most about him being blacklisted is while I agree he was saying and doing stuff that would have been better said in non-sports interviews in the off-season (wearing a Castro shirt in Florida, and saying it was because Cuba has universal health care?? WTF?). But I used to follow him some and in the last several years he really hasn't said or posted anything controversial, at all. He just talks about civil rights, fundraisers, and historical precedent. This has told me more about the NFL than it has about Kap, unless some owners/GMs/scouts/coaches did actually talk to him off the record in recent times, and found out despite posting tame stuff, he actually still was a powder keg waiting to blow. Who knows??
