Toon is the second- or third-best receiver in franchise history, so Mims has got a long way to go to be mentioned in the same breath as him. As others have said, I've been impressed with his consistent blocking, doing the hard work even when he was unhappy with how he was being used.
Gents, I said he reminds me of Toon in tall, fast and can block. Not Toon's ability to get open and make all the catches....
