The left side of their line, with Mulitalo and Ogden, is very good. When Ogden was out, Jamal suffered. With him back in the lineup, he's been able to run better. As long as those two guys are up front, they can plug in anyone else and be able to get at least decent production from them.
Boller is another one of Billick's Frankenstein monsters (see Chris Redman) who doesn't look like he can handle the pros. I could be wrong, but so far, he's shown very little.
