Noted I drink a lot so the memory gets fuzzy at times. The bottom line is Cecil never went into a "downward spiral" on the field. The kid ran as hard and as fast as he could every single play. Not the same with Gilbert who has the same opportunity. Their downfalls are not the same. The trajectory may align but the reasons do not.
In terms of upside, I think Cecil and Gilbert both had unlimited potential and both would have gone down as two of the greatest players in LSU and SEC history had they stayed on the right path. IMO, those two were "once in a lifetime" type players, and based strictly on talent, I would take Cecil over LF and Gilbert over Bowers from Georgia. I know most won't agree, but Cecil and Gilbert's talent levels were off the charts! Now off the field, I wouldn't touch either one with a 10-foot pole!
Bowers is an all-around TE. Gilbert is a wannabe WR in a TE’s body. Bowers like our own Mason Taylor, is willing to do the dirty work (blocking).
I totally agree with what you said. Bowers is an absolute monster and is going to be a beast in the NFL simply because of his hunger to be the best. I still think Gilbert has more upside with his size, speed and hands, but he doesn't have the intangibles and that's what separates the good players from the great players.
Shepard came in all-world, but could never find the field on a consistent basis. Clearly, he had talent, so I have often wondered what was the real story with him. He made it to the NFL and I believed stayed a little while. Players like Shepard and Gilbert just make you wonder how a "can't miss" player with all the talent in the world can fall so quickly.
