Lane, Neal reminds me of Foster, I think he will make an outstanding pro but he won't get his ball security issues under control until he is a pro. Therefore if Neal garners to much playing time he will cost us key games by losing fumbles in key games just as Foster did.
Also using NFL example I prefer a steady 4 to 5 yards per carry over losing 3 on one carry gaining 20 on the next and losing 10 more trying to reverse the field yet again on the 3rd carry. The old I'd always start an Emmit Smith over Barry Sanders if they were on the same team. Give me the dependable 4 to 5 with the occasional long run, over less overall dependability and the slightly higher big play average.
That is why I'd start Lane over Neal, he is just a better and more dependable back in all areas of the game.
