With Tonyan getting 67 targets last season while mostly not being overly productive I truly believe an impact tight end could easily get 110 balls thrown his way.
It didn't take Rodgers long to build chemistry with either Finley or Cook.
Finley had 676 receiving yards in only his second season with the team (after playing only 88 snaps on offense during his rookie campaign) while the team featured two 1,000 yards receivers in Driver and Jennings.
Cook had six receptions for 105 yards and a touchdown in only his fourth game with Rodgers. In the last six games of his only season with the team he caught a total of 31 passes for 407 yards. Those numbers would result in a 88 catch, 1,153 yards season over 17 games.
Rodgers targeted Cook a total of 53 times over the last six games of the 2016 season. That average would result in 150 targets over 17 games.
The best predictor for success is opportunity.
Finley got 12 targets in his first season as a rookie. His second season he got 70. Again, this is nowhere near 110. His best season he got 92. Again, it often takes rookies YEARS to develop into a legit weapon.
Cook was a 7-year vet prior to signing with the Packers. One may be able to argue that IF we were to get Waller that he may have a similar impact. Although, I am doubtful we will. It was a tale of two seasons with Cook, he really picked up towards the end not counting the blowout loss against the Skins.
Martellus Bennett averaged 5 targets per game before getting canned. Tonyan has already been discussed - he probably deserved more targets and I doubt he's back. Jimmy Graham topped out at 90 targets.
Pitts was seen by many to be a "generational TE" and was drafted at pick 4 of the first round as a result. He's 6'6" 245 and runs a 4.40. He was heavily targeted his first year out of necessity considering their WR room and losing Ridley. Waller would be a pretty similar physical specimen, running a 4.46 with a similar build. But he's 31 in September, so I think would be a one or two-year rental at best.
