While I know it is frustrating, a couple of things to keep in mind.
1) The Lions have been active on Day 1 the past few years
2) Players signed within the first 48-72 hours of FA are typically way overpaid
3) Are we so easily forgetting about the Shaun Rogers deal - the biggest of the off season? They also signed Raiola
4) Most of all, we got BOTH of the Walkers back - we can't be too greedy!
Patience young grasshopper!
