I think Rodney leaving is more likely than most realize. I also think the Chip love here is a little over the top. He's a bench player. However, another player transferring (any player) may be cause for concern.
Here is my biggest issue sometimes with how people view transfers. They blame Tubby every single time a guy transfers. Not saying all are not his "fault", but just hear me out.
In basketball, you'd usually have an 8 man rotation. That's what most coaches do and what many on this board want as well. The thing is, you have 12 scholarship players. You have 12 guys getting the same compensation. It is not the NBA where you compensate guys differently based on their ability and where that is their job and guys are more willing to be player 9-12.
On the Gophers, you assume you play the five best guys. EE, Ralph, Joe, Andre, Welch, Austin, Rodney with one spot left in the rotation between Oto, Chip, Ingram, and Mav. Depending on the need each game for that 8th spot, 3 of those guys are not going to see significant minutes. Next year, Ralph will be replaced by Mo in the rotation. So you'll have the same situation except you add two freshman (one of which is a guard too) that could also be fighting for that 8th spot.
Obviously, in that situation someone will be unhappy and likely transfer. Yeah, it sucks Colton is gone NOW, but can you blame him for leaving as a senior and being the likely 4th or 5th big? (behind Mo, Ralph, and Trevor - plus if Rod plays the 4 occasionally). No senior is going to stay in that situation regardless of coach. Guys get recruited over. It happens and they leave. It happens at every single school. Had Mo Walker and Trevor Mbakwe not come along or Royce White (had he played) and it was the Colton/Ralph show for 4 years Colton doesn't leave. So if you want to blame Tubby that transfer you are blaming him for signing Trevor and Mo. If Chip or Mav leaves, then blame him for signing Welch, Coleman, Andre or Ellenson.
I have no issue with transfers if it is due to them being recruited over. In the cases of Royce, Cobbs, and Devoe that was not the case. But when you only can give out so many minutes, someone is going to have to sit. And you hope that they either are okay with that and understand their role, or you hope they work harder for it and look to earn minutes, but then they take it from someone else and then they could get unhappy.
Tubby can't worry about "hurting feelings" when playing guys, he has to worry about winning. I like Chip. I like Mav. I think they are decent players, Chip is a bit better though. But if I had to choose between giving minutes to Chip or Joe, Andre and Welch. I'm taking Joe, Andre, and Welch every time.
Do I want to see someone leave? Absolutley not. In no way shape or form would I like to see a guy transfer, but the truth of the matter is, some guys are not happy sitting on the bench (especially as upperclassmen like Colton) and if that happens, chances are they transfer. However, you hope that in those cases we have a viable plan. With Colton leaving they had Mo (Whoops) and Trevor (Double Whoops) and Ralph (Tripple Whoops). With Chip or Mav leaving you have Welch, Andre, Joe, Austin and Ellenson.
Especially if you can replace Chip with Woodard, who as a freshman may not expect big minutes right away. Or Nolan who is a big and there is less of a log jam there.
IMO, the transfers of Royce, Devoe, and Cobbs have not hurt Tubby for the talent aspect as much as they've hurt the minutes aspect. What Bo Ryan does VERY well is he recruits classes and develop and then they step in. When his SF, for example, graduates he has a junior ready to step in. When guys of different classes leave at once and you replace them with guys of the same class, it messes that plan up. You don't want 5 player recruiting classes you want 2-3 player classes so that you have an evenly distributed team. When you can't "re-load" every year that is how you build. When you bring in those big classes you have to use red shirts creativley (part of the reason I think they had Mo sit this year) to break the class up. Transfers that are not due to being recruited over don't just kill you talent wise, but class set up as well.
It will be interesting to see if anyone does leave, but if it is Mav or Chip I think we have enough talent in front of them that it isn't the end of the world, plus it breaks up that Sophomore class even more.
However, all that said. I hope none of them leave and continue to grow and get better as a team together.
