That's a pretty simple assessment that does not take into account something like who can afford to pay "any" tuition. Or who may have been told that they would get an offer for 1 year and then it would be year to year.
I think Eli's parents are major loaded with cash and getting a chance to play D1 was important to him. He was ready to pay his way other places and we just don't know what happened. Tad could have wanted him as a walkon and then was able to tell him, "Hey - I got a scholarship for at least the first year and we'll see after that".
Bottom line, Tad has 3 kids coming in and he's had a contingency plan all along. Had to.
This makes some sense, may explain how the entire commit happened and the timeline for it.
