I think it suits both team and rider - he hasn't accumulated enought points to make him valuable to a Pro Tour team, but at the same time he gets to ride in most of the races he wanted to ride in anyway, and probably as leader, which would not have at all certain in any Pro Tour team. I'm just a bit depressed that MTN-Q keeps signing more and more non-African riders and is in danger of becoming more like any other team.
According to Smith there will be 12 Africans, so about 8 non- Africans. An alternative would be to go for 18- 20 Africans along the RusVelo or Polsat model ....purely nationalistic, ride round at the back much of the time and few wild cards.
Rome wasn't built in a day. There are good African riders in the team but some lack experience. What will they gain if they cannot get in big races and do not have quality and more experienced riders to learn from? In time they can move to a predominantly African squad, but it may initially take a few more years of compromise.
