If we don't pick up a Guard AND a center you can expect just about the same this year as last.
We're fine at Center. We need two new guards. We all knew that it would take 2-3 years to rebuild or fix the Oline. This is year 2. We're on schedule. It'd make alot more sense to add two new guards (1 FA---Nicks, and 1 draft---DeCastro or Glenn) and go with Kowalski that one year at Center. If Kowalski doesn't perform, then the following year, you draft a Center, and then your set. What better way to bring in a Center with a setup like that already in place? But if he works out, then we can focus on other places.
