Draft another QB while we can (Fields or Wilson) and let them compete. YTF not? If Tua is better, he'll beat out either of them anyhow. I'm quite sure the Jets, Bills, and Pats DON'T want the Dolphins to have two, solid, young QBs. Name a QB who hasn't gotten hurt or had to sit out during his career.
If Grier and company don't get another QB just in case, it'll be yet another horrible decision. Like taking Iggy in the first leaving a half dozen great receivers on the board. Most better than Rugs and Jeudy. (Jefferson, Pittman, Claypool, Higgins, Shenault, Mims, Gabe Davis, etc...)
