Probably not what you want to hear, but I read an article on Henry Brooks prior to his Minnesota visit where he was quoted as being interested in style of play and academics. Since that time, Henry has received an offer from Bruce Pearl who offers a much more appealing style of play. I would guess that Tennessee is now the favorite for Henry. I hope I am wrong with that assumption.
The only word that came out on Welch was that he was thinking strongly of committing if his visit went well this weekend, but that his parents wanted him to take a second visit to have something to compare Minnesota to. According to Marcus' or Myron's twitter that second visit would likely be to Utah.
