Rosen got $18M fully guaranteed. You don't think Murray is expecting more than that? Mayfield got $32M guaranteed.
Your brand as an NFL QB can be worth more way more from endorsement deals than a guy playing in the minors for who knows how long.
When he got a 2nd or 3rd round draft grade initially the baseball money was looking better, so he took it. Once his team got his hype up and was looking like top 5 the money from NFL started looking much better so he changed his mind.
I have no problem chasing the most money, just be honest about it and just know that if he doesn't get a top pick your pick might end up wasted. Likewise are we desperate enough to spend 30M+ for a QB will some significant question marks? I don't think we are right now.
