I will do this. Since Sharp's stock price is pretty high right now, and Lecavalier's price is really low. I don't expect Stamkos continue to play at this level for the entire season, Vinny is still the top line C.
Sharp on the other hand is likely to play 2nd line, if Hossa starts heating up. In fact he is currently listed as a 3rd line Center, and with the depth of the Hawks on the wings and shallow in center, Sharp will likely continue to center lines, which will affect his production a bit.
Lastly, Sharp's 4.2M price tag in a cap-tight team such as Chicago, he will likely be dealt away and this unknown factor will affect his value.
So do this now, before the window of opportunity expires.
