A receiver is only as good as his opportunities. If a guy like Hartline, proven to be at the bottom of the league in terms of production as a starting receiver, is out on the field, we will never know what we have in anyone else. Seeing as we have a new offense that Hartline hasn't even been on the field for, now is just as good of a time as any to cut ties.
Nobody knew who Laurent Robinson was until he get a chance on the field last year. Wes Welker spent years not even working as a receiver before becoming the best slot man in the league. I don't think any of our guys are that good, but there's actually a pretty good chance they could end up being more productive than Hartline, considering how hard it would be to not do that given time on the field.
