Betts a better signing than you thought

[BeastsoftheNFCeast]

Having a 2nd starting calibur RB should be better for many reasons, some obvious and some not. My Reasons are...
1. In case one of them gets injured, we have another
2. Both are less likely to get injured with less runs
3. Both will preform better towards the end of the game due to more energy
4. Portis will probably restructure his contract and get much less than if Ladell wasn't with us (which means more money towards the cap), because he does not carry us anymore and is worth less than when he did.
5. If something goes wrong, we have an extra back we can trade to fix whatever went wrong.
6. Thats one less good RB that other teams can get (it could matter alot depending on who picked him up, lets say the Eagles with their lack of a run game or the Giants with Tiki retireing?)
7. The opposing coaches cant gameplan as officiently because Portis and Betts are two different style of runners.
8. A defense that Portis's style of run is bad on, Betts's might be good, and vica versa.
9. When one is having a bad game, the other might be having a good one, so we will almost never have a terrible run game.
10. Opposing defenses won't get used to and pick up the moves of each runner as easily because they will have to experience two different runners and styles.
