I don't know if Dooley has established himself as the high caliber coach that UT needs to continue its climb back to the SEC (his record is inconclusive at best), but on the character side, he will run quality program, recruit motivated good young players and respect/enhance traditions. Fans need to give him a couple of years to get through the turmoil and let him do his thing before railing on him.
BTW, while wrestling ain't football, Tom Brands did a similar thing to VT a couple of years ago and the only issue most had with him leaving for his dream job at Iowa was that he took his top recruits with him after redshirting them for a year and after driving off some decent wrestlers - pretty much leaving the team in shambles. The current coach, Kevin Dresser (also an Iowa alumnus - but a man of quality) has done a great job pulling the team back together and making it competitive. Let's hope Dooley does the same.
