From the second we showed some interest in Gathers, I thought he would eventually play offensive tackle. Although, the idea of a TE that big and athletic is incredibly tempting. The last 2 "project" players I liked as future offensive tackles was an overweight tight end at Arkansas and a 6-foot-9 wide receiver at Army (Pro-Bowler Jason Peters and Steelers starting LT Alejandro Villanueva).
Gathers played at Baylor at a very lean 265 lbs. That's college basketball shape. Their conditioning and weight training is very different from that of a college football player, let alone an NFL player. Now, he's reportedly at 290 lbs., and showing real potential as a blocker. He's got basketball feet and incredibly long arms. If he can master the technical aspect, he would be incredibly tough for pass rushers to get around.
I have a feeling that the 2018 starting O-Line will look like this:
LT Tyron Smith
LG La'el Collins
C Travis Frederick
RG Zack Martin
RT Rico Gathers
I also think he is on the 53 next year and ends up the swing tackle if Chaz Green continues to struggle with injuries.
