Tubman is a 4* on 247, and for good reason. He only started playing football recently, so he's pretty raw, but he's 6-4, 235, and runs a 4.5 40. He's bigger, stronger, and faster than Aaron Maybin at this point in his career. He's monstrously athletic, and with good coaching, could turn out to be a BEAST.
Sorrel is a TE who projects as a LT. He's got a massive frame that he'll need to fill out, and probably won't contribute for at least 3 years, but has a lot of upside. Very similar to Noah Beh actually.
Also worh noting that both kids de-committed, and then contacted Coach Franklin, and weren't targeted. They got offers when they called him up.
