Just a little research, all answers are appreciated :)
That is a terrible deal, I don't care who is on your roster.
Yeah not enough information here. However some things to look at. If it's a newer car 88 or newer, and the car is not STARTING but will crank. It’s likely you have a bad Cam or crank sensor, bad fuel pump, or bad injectors. If the car will not CRANK, then you need to see if you can turn the motor by hand. If you can then your motor is not seize. You need to start tracing wires. If you are not getting any power down to the starter I would look at a bad fuse, bad battery cables, bad wires to the starter, bad ground at the starter, or something in the relay section. Hope this helps, with the limited information you gave it is very difficult to troubleshoot.
I think you need to accept her for who she is and accept that this happened before the two of you were together. She was not cheating on you as this was before your time. I believe that what happened before your time is her business and should not concern you too much. It is a problem if this happens when you are faithful and together, but this was before your time. She has trusted in you and told you of this when she did not have to and this is a sign of trust in my opinion. Good luck, but I think you need to accept her past and focus on the now and the future.
Cant give my opinion, I have no idea who is currently on your roster.
Not worth it. You do not know what kind of chemistry Trent Edwards and TO will have and Mendenhall is not a starter. Neither one of those players are worth losing a first pick or worth losing Witten,.
