I try to mix it up a bit too. Seems to keep me interested for months. Here's what I did for this years game.
I accepted the Bowling Green coaching job to start my dynasty. Then I set the playbook to what I feel would work best with my teams talent. In this case I used Arizona and run either a Multiple D or 3-3-5 depending on my opponent. Another thing I tried was switching to an Independent so I could pick my entire schedule while still retaining my rivalry games. I was bowl eligible in my 2 seasons but played some easy teams due to my teams overall lack of talent.
As I head into the 3rd season I am amazed at the 2 job offers that become available. USC or Ohio State. I choose USC due to the fact Barkley, Woods, Prater and Baxter are still all there! I run an Air Raid and throw for record setting numbers half way through the season but then decide I'm gonna see what happens if I quit my job then find a new one just messing around of course.
Or not. I accept the best job available. Oregon! Wow. LaMichael James as a 99 everything senior with a superfast QB running the Oregon spread offense. Now I'm hooked! I think I found my new favorite offense and team especially with all the uniform options and pipeline recruiting states Oregon, Cali, Texas & Louisiana. This is gonna be fun
