Tyler was my roommate on USA West this past summer so we talked about his desire to transfer pretty extensively. I think he wanted to play at a more competitive level and have a chance or two at a Div A national championship, plus he liked the guys on our team that played for CSU and he saw how good of a coach Flip is. He talked about transferring with many of us, but I don't think most of us thought he actually would. When I saw him in Vegas in a Rams jersey, I was a bit surprised to say the least
To partially answer your recruiting question, I never saw Flip pressure Tyler to come to CSU in any way. I don't know what they talked about in private, but I don't think Flip's the type to actively recruit players away from other programs. I'm not really sure about their recruiting other than that, but I can't think that the CSU name and history would hurt their recruiting efforts...
Flip switched him from attack to middie this fall because he wanted him to work on moving his feet more (instead of relying on his stickwork and fakes). I'm not sure if he's been moved back to attack or not, but from what Tyler told me, he's having a good time at CSU and is glad to be a Ram.
