Yup, I know Arkansas has some heavy financial backing, don't forget that TCU has old school oil money in Ft Worth, I'm not saying they have more money that Arkansas, just that they have some deep pockets - their endowment is barely bigger, both are just over $1B.
I fully expected Patterson would leave TCU for Arkansas for the reasons you mentioned above, I don't get a position coach doing a lateral... that's all.
I think its a good hire for Arkansas btw.
