Where can I see my players overall ratings going up or down

Doesn't look like the player page Ratings Progression graphs track the OVR number.
Just gonna toss this idea out. You might want to create a spreadsheet file (excel or open office) for your team to track OVR and Salaries at each position. You can add notes and do your planning on the spreadsheet. Makes doing some things much easier and it works better for getting a big picture of your team.
