Green Bay has NEVER had a TE in it's history that was close to Rob Gronkowski. Keith Jackson wasn't even close.
Really now ?
Paul Coffman (1978-85) 39 TD 4,223 yards...... just as good of a receiver as Gronk and he played with rules that didn't favor the receiving TE.Coffman was selected to three Pro Bowls
Marv Fleming (1963-69) He was the first player to appear in five Super Bowls: I and II with the Packers, and Super Bowls VI, VII and VIII with the Dolphins, including the 1972 undefeated team. Fleming also won the 1965 NFL title with Green Bay. Not huge he played when the TE wasn't as big a deal.. tough SOB would have sent Gronk calling for his momma.
Ron Kramer (1957, 1959-64) From 1960-64, Kramer hauled in 142 passes for 2,257 yards and rumbled for 15 TDs. Kramer is defined by his contribution to Lombardi’s power sweep, in which Kramer lined up outside the tackle and nailed linebackers, creating either the inside or outside crease the famous coach drilled for endlessly in practice. Despite his devastating blocking, Kramer also had the speed to get loose in the secondary, and he was a quick option for Bart Starr on a blitz. Again a player tougher then Gronk ever imagined being.
I can go on but won't. Please quit quantifying your argument with NEVER if you really don't know. Your argument for a better receiving TE is valid but it comes unhinged when you try desperately to spew packers hate regarding personal and management.
