If you're drafting an OT with the first pick, you're not gaging anything. You don't franchise tag a LT and then draft his replacement unless you plan on losing several of your own free agents...that's a $15 million dollar gauge...that makes no sense and it's bad business. You're certainly not going to be players in the free agent market if you tie up more than 12% of you cap space on one player.
Lemonier is more of a tweener to me. Undersized DE, good fit in the 3-4, high motor, good pass rush moves. Not sure how he would hold up against the run in the NFL.
I don't like Tavon Austin in the 2nd...not enough value for me. He's a slot receiver at best so you've essentially negated Bess who should be in the slot and not on the boundary and still haven't addressed the boundary where we need the most help.
