Silly Season is in full swing, but is there a lack of up and coming drivers?

Silly Season started fairly early this year with Dale Earnhardt Jr.'s announcement.  We all know where he's going and we are pretty sure where Kyle Busch will end up, but what of other seats that may need to be filled?

There is a lack of up and coming drivers in the Busch and Craftsman Truck Series that will be ready in a year or two to make the move to the Cup Series.  The Craftsman Truck Series barely sends anyone home on any given weekend, the Busch Series has had trouble filling the 43 slots each week and that's with having almost half the field being Cup drivers at times. 

We've all heard that J.J. Yeley's ride at JGR is in jeopardy, we've heard that RCR might be planning on adding a fourth car next year, Penske may add a third car in 2009 and what about the Toyota drivers, I'm sure some of their rides are in jeopardy too.  In fact Waltrip is stepping out of the car and allowing Terry Labonte to race the car for the road courses, to help them.

Who is going to be there to fill those seats?  There's not a lot of young guys out there that are ready for the move, so where do they get the drivers?  Do they go to ARCA, pick a talent from there and hope for the best?  I don't think many teams even have developmental drivers that are close to being ready either, so that makes it harder to get that perfect fit of driver and team.

It used to be that a driver worked his way up, Truck, Busch and then Cup, but now you don't have the same atmosphere in either of the lower series for that to happen and that puts us in the situation we see today, there could be lots of rides available and not enough talent to fill them.

Your thoughts?
